PROXY STATEMENT

2011 ANNUAL MEETING OF STOCKHOLDERS

OF

IRON MOUNTAIN INCORPORATED

This proxy statement and accompanying GREEN proxy form are being furnished to stockholders of Iron Mountain Incorporated, a Delaware corporation (the “Company”), by Elliott Associates, L.P., a Delaware limited partnership (“Elliott Associates”), and Elliott International, L.P., a Cayman Islands limited partnership (“Elliott International”) (for convenience throughout this proxy statement we sometimes refer to Elliott Associates and Elliott International collectively as “Elliott,” “we”, “our” or “us”) in connection with the solicitation of proxies from you, the holders (the “Stockholders”) of common stock, par value $0.01 per share, of the Company (the “Common Stock”), in connection with the 2011 Annual Meeting of Stockholders, including any and all adjournments, postponements, continuations or reschedulings thereof, or any other meeting of stockholders held in lieu thereof (the “2011 Annual Meeting”).

This proxy statement and the accompanying GREEN proxy form are first being sent or given on or about [                    ], 2011 to all holders of Common Stock as of the Record Date (as defined below).

We intend to vote all solicited proxies at the 2011 Annual Meeting scheduled to be held on [            ], [    ], 2011, commencing at [            ], local time, at [                    ], in order to take the following actions:

1. vote “FOR” the election of Ted Antenucci, Robert J. Levenson, Allan Z. Loren and Harvey Schulweis (each, a “Nominee” and, collectively, the “Nominees”) to serve as directors on the board of directors of the Company (the “Board”) until the 2012 Annual Meeting of Stockholders or until their respective successors are duly elected and qualified;

2. vote “FOR” the repealing of any provision of or amendment to the Amended and Restated By-laws of the Company (the “By-laws”) adopted by the Board subsequent to March 5, 2010 without the approval of the Stockholders (the “Stockholder Proposal”);

1

3. vote “FOR” the Company’s proposal to ratify the selection by the Audit Committee of the Board of the Company (the “Audit Committee”) of the firm of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ended December 31, 2011;

4. vote “FOR” the Company’s non-binding resolution concerning the compensation of the Company’s named executive officers, as described further in the Company’s [Preliminary] Proxy Statement on Schedule 14A, filed with the SEC on [                    ], 2011 (the “Company’s Proxy Statement”);

5. vote “FOR EVERY YEAR” on the Company’s proposal for a non-binding, advisory vote on the frequency (every one, two or three years) of future advisory votes of Stockholders on the compensation of the Company’s named executive officers, as described further in the Company’s Proxy Statement; and

6. transact such other business as may properly come before the 2011 Annual Meeting.

Under the proxy rules we may solicit proxies in support of our Nominees and also seek authority to vote for all of the Company’s nominees other than those Company nominees we specify. This allows a Stockholder of the Company who desires to vote for up to a full complement of twelve director nominees to use the GREEN proxy form to vote for our Nominees as well as the Company’s nominees for whom we are seeking authority to vote other than those nominees as to which the Stockholder specifically withholds our authority to vote. We have determined to nominate a slate of four Nominees, Messrs. Antenucci, Levenson, Loren and Schulweis and are seeking authority to vote for up to all of the Company’s nominees other than [                    ]. As a result, should a Stockholder so authorize us, on the GREEN proxy form, we would cast votes for our four Nominees and up to eight of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote have agreed to serve with any of our Nominees, if elected.

THE PARTICIPANTS URGE YOU TO VOTE THE GREEN PROXY FORM “FOR” TED ANTENUCCI, ROBERT J. LEVENSON, ALLAN Z. LOREN AND HARVEY SCHULWEIS AS DIRECTORS.

The principal executive offices of the Company are located at 745 Atlantic Avenue, Boston, Massachusetts 02111. The Company has set the close of business on [                    ], 2011 as the record date (the “Record Date”) for determining the Stockholders entitled to vote at the 2011 Annual Meeting.

Stockholders of the Company as of the Record Date are entitled to one vote at the 2011 Annual Meeting for each share of Common Stock of the Company held on the Record Date. It is anticipated that the definitive proxy statement that will be filed by the Company in connection with the 2011 Annual Meeting will state the number of shares of Common Stock issued and outstanding on the Record Date. According to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010 filed by the Company with the Securities and Exchange Commission on March 1, 2011 (the “Company 10-K”), as of February 10, 2011 there were 200,194,653 shares of Common Stock of the Company issued and outstanding. As of March 30, 2011, Elliott Associates is the direct record owner of 1,000 shares of Common Stock and is the beneficial owner of an additional 4,189,388 shares of Common Stock, and Elliott International is the direct record owner of 1,000 shares of Common Stock and is the beneficial owner of an additional 5,486,488 shares of Common Stock, which together represents approximately 4.83% of the issued and outstanding shares of Common Stock (based on information disclosed in the Company’s 10-K regarding the number of issued and outstanding shares of Common Stock on February 10, 2011).

In addition, (i) Paul E. Singer (“Singer”), Elliott Capital Advisors, L.P. (“Capital Advisors”), which is controlled by Singer, and Elliott Special GP, LLC (“Special GP”), which is controlled by Singer, are the general partners of Elliott Associates and may all be deemed to beneficially own the shares of Common Stock held by Elliott Associates, (ii) Singer, Braxton Associates Inc. (“Braxton”) and Elliott Asset Management LLC (“Asset Management”) are the general partners of Capital Advisors and may be deemed to beneficially own the shares of Common Stock held by Elliott Associates, (iii) The Liverpool Limited Partnership (“Liverpool Partnership”), a wholly-owned subsidiary of Elliott Associates, initially acquired a portion of the shares of Common Stock

2

beneficially owned by Elliott Associates, as described on Annex A hereto, and Liverpool Associates Ltd. (“Liverpool Associates”), a wholly-owned subsidiary of Elliott Associates, is the sole general partner of Liverpool Partnership and may be deemed to beneficially own the shares of Common Stock held by Liverpool Partnership, and (iv) Elliott International Capital Advisors Inc. (“EICA”), as investment manager of Elliott International, Hambledon, Inc. (“Hambledon”), which is also controlled by Singer, as the sole general partner of Elliott International and Singer, may be deemed to beneficially own the shares of Common Stock held by Elliott International (Singer, Capital Advisors, Special GP, Braxton, Asset Management, Liverpool Partnership, Liverpool Associates, EICA, Hambledon and Elliott Management Corporation, which provides management services to Elliott and their affiliates, collectively the “Elliott Participants”).

We intend to vote all of the Common Stock that we beneficially own at the 2011 Annual Meeting “FOR” the election of our Nominees and to grant authority to vote for the Company’s nominees other than [                    ], “FOR” our Stockholder Proposal, “FOR” the Company’s proposal to ratify the selection by the Audit Committee of the firm of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ended December 31, 2011, “FOR” the Company’s non-binding resolution concerning the compensation of the Company’s named executive officers, “FOR EVERY YEAR” on the Company’s proposal for a non-binding, advisory vote on the frequency (every one, two or three years) of future advisory votes of Stockholders on the compensation of the Company’s named executive officers, and in our discretion with respect to such other business as may properly come before the 2011 Annual Meeting.

We are soliciting your vote because we believe that, in recent years, Company management has failed to capitalize on the strengths of Iron Mountain’s business in order to maximize value for stockholders. We believe the Company has an excellent core business with a sustainable competitive advantage, but that stockholder value has suffered from an over-allocation of capital to digital and international physical storage investments and an inefficient corporate structure. We believe the Board must launch an in-depth review of the Company’s capital allocation and operational efficiency, including a review of the Company’s recent and planned capital investments as well as the merits of its status as a fully taxable “C” corporation. To that end we have assembled a slate of four independent, highly qualified and motivated individuals who are fully prepared to explore all options to maximize stockholder value. We believe our nominees have exceptional experience and will bring fresh, independent perspectives and additional insights to the Board’s review process. We urge the Stockholders to send a message to the Company by voting “FOR” our Nominees and the Stockholder Proposal described in this document.

This proxy solicitation is being made by Elliott and not on behalf of the Board or the Company’s management.

In 1966, he partnered with the founder of a then-recently formed data processing services company, Central Data Systems, Inc., a start-up that floated its initial public offering in 1968 and that was ultimately acquired by ITEL Corp. At ITEL, Mr. Levenson was Group Executive Vice President when he resigned in 1980. For the following twenty years, beginning in 1981, Mr. Levenson held senior executive positions at: Automatic Data Processing, Inc. (“ADP”) from 1981 until 1984 and served on ADP’s Board of Directors from 1984 until 1990, Medco Containment Services, Inc. from 1990 until 1993, including service on Medco Containment Services, Inc.’s Board of Directors during that period, and First Data Corp. from 1993 until 2000 and served on First Data Corp.’s Board of Directors from 1992 until 2003.

Mr. Levenson has a Bachelor of Science degree in Accounting from Kent State University (1963). Elliott believes that the attributes, skills and qualifications Mr. Levenson has developed through his extensive experience as an executive in the data processing industry will allow Mr. Levenson to provide key industry insight along with judgment, wisdom and perspective. In addition, Mr. Levenson brings to the Board financial experience as evidenced by his background in accounting as well as his service on the audit committees of Elite Pharmaceuticals, Emisphere Technologies, Inc., Vestcom International and Superior Telecom.

Elliott believes that the attributes, skills and qualifications Mr. Loren has developed through more than 50 years of executive experience with D&B, American Express, Galileo International, Apple Computer and Cigna as well as through his work as an executive coach to Chief Executive Officers, will allow Mr. Loren to provide the Board and the Company with a highly developed business and technology acumen and leadership experience along with a valued perspective on macro and micro issues alike.

		Mr. Schulweis has been a member of the audit committee of The Town & Country Trust as well as a member of the audit committee for large not-for-profit entities including The UJA-Federation of New York (for the past five years) and Yeshiva University (for the past two years). Mr. Schulweis has also served as a member of the Budget and Finance Committee of the American Jewish Joint Distribution Committee for the past three years. Other than as Chairman of the Board of The Town & Country Trust, as disclosed herein, Mr. Schulweis does not presently serve, and has not in the last five years served, as a director of any public company. Elliott believes that the attributes, skills and qualifications Mr. Schulweis has developed through his more than 30 years of experience in real estate investment management will provide the Board and the Company valuable technical expertise and leadership. In addition, Elliott believes Mr. Schulweis’ experience as a general partner of a major public accounting firm, an international investment banking firm and as the CEO of an NYSE company will provide the Board and the Company with significant leadership experience in the areas of finance and accounting.

The Board currently consists of twelve directors, all of whom are in the same class and up for election at the 2011 Annual Meeting. According to the Company’s Proxy Statement, the Board of the Company intends to nominate twelve candidates for election as directors at the 2011 Annual Meeting. This proxy statement is soliciting proxies to elect Messrs. Antenucci, Levenson, Loren and Schulweis, and to grant authority to vote for the Company’s nominees other than [                    ]. Therefore, should a Stockholder so authorize us, we will cast votes for our four Nominees and up to eight of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote have agreed to serve with any of our Nominees, if elected.

11

If elected, the Nominees will be a minority of the directors and will not alone be able to adopt resolutions or otherwise cause the Board to act. However, the Nominees expect to be able to actively engage other Board members in full discussion of the issues facing the Company and resolve them together. By utilizing their respective experiences and working constructively with Board members, the Nominees believe they can effect positive change at the Company.

The corporate governance guidelines of the Company, which are available on the Company’s website at www.ironmountain.com, provide that determinations of independence shall be made in accordance with the criteria for independence required by the New York Stock Exchange. Except as otherwise disclosed in this proxy statement and on Annex A hereto, we believe the Nominees are independent within the meaning of the listing standards of the NYSE and the corporate governance guidelines of the Company. In addition, except as otherwise disclosed in this proxy statement and on Annex A hereto, we believe that the Nominees are independent under the heightened independence standards applicable to audit committee members under the rules of the NYSE and the SEC. No Nominee is affiliated with Elliott or any subsidiary of Elliott or has any relationship with Elliott (except as otherwise set forth in this proxy statement, including his agreement to serve as a Nominee as described in this proxy statement under “Arrangements between Elliott and the Nominees” below).

You should refer to the Company’s Proxy Statement and form of proxy distributed by the Company for the names, background, qualifications and other information concerning the Company’s nominees.

Who can vote at the 2011 Annual Meeting?

According to the Company’s Proxy Statement, the only securities eligible to be voted at the 2011 Annual Meeting are shares of Common Stock. Only Stockholders of record at the close of business on the Record Date, [                    ], 2011, are entitled to vote at the 2011 Annual Meeting. Each share of Common Stock represents one vote, and all shares of Common Stock vote together as a single class. There is no cumulative voting. It is anticipated that the definitive proxy statement that will be filed by the Company in connection with the 2011 Annual Meeting will state the number of shares of Common Stock issued and outstanding on the Record Date.

How do proxies work?

Elliott is asking you to appoint [            ] and [            ] as your proxy holders to vote your shares of Common Stock at the 2011 Annual Meeting. You make this appointment by voting the enclosed GREEN proxy form or by using one of the voting methods described below. Giving us your proxy means you authorize the proxy holders to vote your shares at the 2011 Annual Meeting, according to the directions you provide. You may vote for all, some, or none of our director candidates. Whether or not you are able to attend the 2011 Annual Meeting, you are urged to complete the enclosed GREEN proxy form and return it in the enclosed self-addressed, prepaid envelope or follow the instructions located on the GREEN proxy form to vote by telephone or Internet. All valid proxies received prior to the meeting will be voted. If you specify a choice with respect to any item by marking the appropriate box on the proxy, the shares of Common Stock will be voted in accordance with that specification. IF NO SPECIFICATION IS MADE, THE SHARES OF COMMON STOCK WILL BE VOTED (I) “FOR” TED ANTENUCCI FOR DIRECTOR; (II) “FOR” ROBERT J. LEVENSON FOR DIRECTOR; (III) “FOR” ALLAN Z. LOREN FOR DIRECTOR; (IV) “FOR” HARVEY SCHULWEIS FOR DIRECTOR; (V) TO GRANT AUTHORITY TO VOTE FOR THE PERSONS WHO HAVE BEEN NOMINATED BY THE COMPANY TO SERVE AS DIRECTORS, OTHER THAN [                    ]; (VI) “FOR” THE RATIFICATION OF THE SELECTION OF THE INDEPENDENT REGISTERED ACCOUNTING FIRM; (VII) “FOR” THE COMPANY’S NON-BINDING RESOLUTION CONCERNING THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS; (VIII) “FOR EVERY YEAR” ON THE COMPANY’S PROPOSAL FOR A NON-BINDING, ADVISORY VOTE ON THE FREQUENCY (EVERY ONE, TWO OR THREE YEARS) OF FUTURE ADVISORY VOTES OF STOCKHOLDERS ON THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS; AND (IX) IN THE PROXY HOLDERS’ DISCRETION AS TO OTHER MATTERS THAT MAY PROPERLY COME BEFORE THE 2011 ANNUAL MEETING.

12

We do not know of any other matters to be presented for approval by the Stockholders at the 2011 Annual Meeting. Unless you indicate otherwise on the GREEN proxy form or through the telephone or Internet voting procedures, you also authorize your proxy holders to vote your shares of Common Stock in their discretion on any matters not known by Elliott at the time this proxy statement was printed and that, under the Company By-Laws, may be properly presented for action by the Stockholders at the 2011 Annual Meeting.

What do I need to attend the 2011 Annual Meeting?

Attendance at the 2011 Annual Meeting or any adjournment or postponement thereof will be limited to Stockholders of record of the Company as of the close of business on the record date and guests of the Company. If you are a Stockholder of record, your name will be verified against the list of Stockholders of record prior to your admittance to the 2011 Annual Meeting or any adjournment or postponement thereof. Please be prepared to present photo identification for admission. If you hold your shares in street name or through the Company’s 401(k) Plan, you will need to provide proof of beneficial ownership, such as a brokerage account statement, a copy of a voting instruction form provided by your custodian or the plan trustee with respect to the 2011 Annual Meeting, or other similar evidence of ownership, as well as photo identification, in order to be admitted to the 2011 Annual Meeting. Please note that if you hold your shares in street name and intend to vote in person at the 2011 Annual Meeting, you must also provide a “legal proxy” obtained from your custodian. Note that 401(k) Plan participants will not be able to vote their 401(k) Plan shares in person at the 2011 Annual Meeting.

What is the quorum requirement for the 2011 Annual Meeting?

The quorum requirement is set forth below and is based on current Article II, Section 2.8 of the By-laws. The presence at the 2011 Annual Meeting, in person or by proxy, of Stockholders entitled to cast at least a majority of the votes that all Stockholders are entitled to cast at the 2011 Annual Meeting will constitute a quorum. Shares represented by valid proxies will be treated as present at the 2011 Annual Meeting for purposes of determining a quorum, without regard to whether the proxy is noted as casting a vote or abstaining. Shares represented by broker non-votes, if any, will be treated as present for purposes of determining a quorum. Shares voted by a broker on any issue other than a procedural motion will be considered present for all quorum purposes, even if the shares are not voted on every matter. In case a quorum is not present at the 2011 Annual Meeting, the holders of a majority of the voting power of the shares of Common Stock present at the 2011 Annual Meeting in person or represented by proxy may adjourn the 2011 Annual Meeting (without notice other than announcement of adjournment at the 2011 Annual Meeting) to another time, or to another time and place.

How many shares of Common Stock must be voted in favor of the Nominees to elect them?

Pursuant to Section 3.1 of Article III of the By-laws, in a “contested” election (as defined in Section 3.1 of Article III of the By-laws) the directors of the Company will be elected by a plurality of the votes cast at the 2011 Annual Meeting, assuming a quorum is present. For this purpose, “plurality” means that the individuals receiving the largest number of votes are elected as directors, up to the maximum number of directors to be elected. In the election of directors, every Stockholder has the right to vote each share of Common Stock owned by such Stockholder on the Record Date for as many persons as there are directors to be elected, and for whose election the shares of Common Stock are entitled to vote. Accordingly, the twelve nominees who receive the greatest number of votes cast by the Stockholders represented in person or by proxy at the 2011 Annual Meeting will be elected as directors. You may either vote for or withhold authority to vote for each Nominee for the Board. If you withhold authority to vote with respect to any Nominee, your shares of Common Stock will be counted for purposes of establishing a quorum, but will have no effect on the election of that Nominee. Your broker is not permitted to vote your shares of Common Stock on the proposal to elect our Nominees without receiving instructions from you. If you hold your shares of Common Stock in your own name, you must vote such shares in person or by proxy or they will not be voted.

13

How many shares of Common Stock must be voted in favor of the other proposals described in this proxy statement?

Proposal 2: Pursuant to Section 2.9 of Article II of the By-laws, the affirmative vote of a majority of the votes properly cast at the 2011 Annual Meeting is required to approve the Stockholder resolution with regard to the repeal of any provision of or amendment to the By-laws adopted by the Board subsequent to March 5, 2010 without the approval of the Stockholders. You may vote for or against or you may abstain on Proposal 2. Your broker is not permitted to vote your shares of Common Stock on Proposal 2 without receiving instructions from you. If you hold your shares of Common Stock in your own name, you must vote such shares in person or by proxy or they will not be voted. Proposal 2 requires a majority of the votes cast for approval.

Proposal 3: Pursuant to Section 2.9 of Article II of the By-laws, the affirmative vote of a majority of the votes properly cast at the 2011 Annual Meeting is required to approve the Company’s proposal to ratify the selection by the Audit Committee of the firm Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ended December 31, 2011. You may vote for or against or you may abstain on Proposal 3. Your broker is not permitted to vote your shares of Common Stock on Proposal 3 without receiving instructions from you. If you hold your shares of Common Stock in your own name, you must vote such shares in person or by proxy or they will not be voted. Proposal 3 requires a majority of the votes cast for approval.

Proposal 4: Pursuant to Section 2.9 of Article II of the By-laws, the affirmative vote of a majority of the votes properly cast at the 2011 Annual Meeting is required to approve the Company’s non-binding resolution concerning the compensation of the Company’s named executive officers, as described in the “Compensation Discussion and Analysis” section of the Company’s Proxy Statement, the compensation tables and the other narrative compensation disclosures contained in the Company’s Proxy Statement pursuant to Item 402 of Regulation S-K. You may vote for or against or you may abstain on Proposal 4. Your broker is not permitted to vote your shares of Common Stock on Proposal 4 without receiving instructions from you. If you hold your shares of Common Stock in your own name, you must vote such shares in person or by proxy or they will not be voted. The opportunity to vote on this Proposal 4 is required pursuant to Section 14A of the Exchange Act. However, as an advisory vote, the vote on this Proposal 4, if passed, is not binding upon the Company and serves only as a recommendation to the Board.

Proposal 5: The frequency that receives the highest number of votes will be considered the frequency recommended by Stockholders in connection with the Company’s proposal to hold non-binding, advisory votes on the Company’s compensation of its named executive officers. The Company has advised in the Company’s Proxy Statement that the compensation committee of the Board will consider the outcome of the vote when making future decisions on executive compensation. However, as an advisory vote, the vote on this Proposal 5, if passed, is not binding upon the Company, and the Board may decide that it is in the best interests of the Stockholders and the Company to hold an advisory vote on executive compensation more or less frequently than the alternative approved by the Stockholders. The Company has advised in the Company’s Proxy Statement that the Board has not yet determined the frequency with which the Company will hold the Stockholder advisory vote on named executive officer compensation required by Section 14A of the Exchange Act or when the next such Stockholder advisory vote on named executive officer compensation will occur. According to the Company’s Proxy Statement, the Board recommends that you vote to hold a non-binding, advisory vote on the compensation of the Company’s named executive officers annually.

If other matters are properly brought before the 2011 Annual Meeting, the vote required will be determined in accordance with applicable law, the New York Stock Exchange Rules, and the Company’s Amended and Restated Certificate of Incorporation and the By-laws, as applicable.

What should I do in order to vote for the Nominees and the other proposals?

If your shares of Common Stock are held of record in your own name, please authorize a proxy to vote by marking, signing, dating and returning the enclosed GREEN proxy form in the postage-paid envelope provided to you by us or follow the instruction on the GREEN proxy form to vote by telephone or Internet.

14

If you hold your shares of Common Stock in “street name” with a bank, brokerage firm, dealer, trust company or other nominee, only they can exercise your right to vote with respect to your shares of Common Stock and only upon receipt of your specific instructions. Accordingly, it is critical that you promptly give instructions to your bank, brokerage firm, dealer, trust company or other nominee to ensure that a GREEN proxy form is submitted on your behalf. Please follow the instructions to authorize a proxy to vote provided on the enclosed GREEN proxy form. If your bank, brokerage firm, dealer, trust company or other nominee provides for voting instructions to be delivered to them by Internet or telephone, instructions will be included on the enclosed GREEN proxy form. We urge you to confirm in writing your instructions to the person responsible for your account and provide a copy of those instructions to us, care of MacKenzie Partners, Inc., at 105 Madison Avenue, 17th Floor, New York, New York 10016, so that we may be aware of all instructions given and can attempt to ensure that such instructions are followed.

YOUR VOTE IS VERY IMPORTANT. If you do not plan to attend the 2011 Annual Meeting, we encourage you to read this proxy statement and date, sign and return your completed GREEN proxy form provided to you by us prior to the 2011 Annual Meeting so that your shares of Common Stock will be represented and voted in accordance with your instructions. Even if you plan to attend the 2011 Annual Meeting in person, we recommend that you authorize a proxy to vote your shares of Common Stock in advance as described above so that your vote will be counted if you later decide not to attend the 2011 Annual Meeting. To ensure that your vote is counted, please remember to submit your vote so that it is received by us no later than [                    ], 2011.

Can I use the GREEN proxy form to vote for any of the Company’s nominees?

Under the proxy rules we may solicit proxies in support of our Nominees and also seek authority to vote for all of the Company’s nominees other than those Company nominees we specify. This allows a Stockholder of the Company who desires to vote for up to a full complement of twelve director nominees to use the GREEN proxy form to vote for our Nominees as well as the Company’s nominees for whom we are seeking authority to vote other than those nominees as to which the Stockholder specifically withholds our authority to vote. We have determined to nominate a slate of four Nominees, Messrs. Antenucci, Levenson, Loren and Schulweis and are seeking authority to vote for up to all of the Company’s nominees other than [                    ]. As a result, should a Stockholder so authorize us, on the GREEN proxy form, we would cast votes for our four Nominees and up to eight of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote have agreed to serve with any of our Nominees, if elected.

What is the deadline for submitting proxies?

Proxies can be submitted until the polls are closed at the 2011 Annual Meeting. However, to be sure that we receive your proxy in time to utilize it, we request that you provide your proxy to us as early as possible.

How do I revoke a proxy?

Any Stockholder has the power to revoke a previously submitted proxy at any time before it is exercised even if you submitted a proxy card or form sent to you by the Company. If you are a registered holder of Common Stock, you may revoke a previously submitted proxy by:

• voting over the internet or by telephone at a later time in the manner provided on the GREEN proxy form;

• signing, dating and returning the enclosed GREEN proxy form in the postage-paid envelope provided;

• delivering to the Secretary of the Company a written notice of revocation c/o Iron Mountain Incorporated, 745 Atlantic Avenue, Boston, Massachusetts 02111; or

• attending the 2011 Annual Meeting and voting in person.

15

Please note, however, that only your last-dated proxy will count—any proxy may be revoked at any time prior to its exercise at the 2011 Annual Meeting as described in this proxy statement. Attending the 2011 Annual Meeting alone without taking one of the actions above will not revoke your proxy.

Stockholders who hold their shares of Common Stock in “street name” with a bank, brokerage firm, dealer, trust company or other nominee will need to notify the person responsible for their account to revoke or withdraw previously given instructions. Unless revoked in the manner set forth above and subject to the foregoing, duly authorized proxies in the form enclosed will be voted at the 2011 Annual Meeting in accordance with your instructions. We request that a copy of any revocation sent to the Company or any revocation notification sent to the person responsible for a bank or brokerage account also be sent to us, care of MacKenzie Partners, Inc., at the address listed above, so that we may be aware of any revocation of a proxy.

PLEASE DO NOT RETURN ANY WHITE PROXY CARD YOU MAY RECEIVE FROM THE COMPANY OR OTHERWISE AUTHORIZE A PROXY TO VOTE YOUR SHARES OF COMMON STOCK AT THE 2011 ANNUAL MEETING, NOT EVEN AS A PROTEST VOTE. IF YOU HAVE ALREADY RETURNED A WHITE PROXY CARD TO THE COMPANY OR OTHERWISE AUTHORIZED A PROXY TO VOTE YOUR SHARES OF COMMON STOCK AT THE 2011 ANNUAL MEETING, IT IS NOT TOO LATE TO CHANGE YOUR VOTE. TO REVOKE YOUR PRIOR PROXY AND CHANGE YOUR VOTE, SIMPLY SIGN AND RETURN THE ENCLOSED GREEN PROXY FORM IN THE POSTAGE-PAID ENVELOPE PROVIDED OR USE THE GREEN PROXY FORM TO VOTE BY TELEPHONE OR INTERNET. ONLY YOUR LATEST DATED PROXY WILL BE COUNTED.

Who is paying for the solicitation on behalf of Elliott?

Elliott will pay all costs of the solicitation of proxies on behalf of Elliott and the other participants described on Annex A hereto for the 2011 Annual Meeting. Elliott does not intend to seek reimbursement of those costs from the Company.

Whom should I call if I have any questions about the solicitation?

If you have any questions, or need assistance in voting your shares of Common Stock, please call our proxy solicitor, MacKenzie Partners, Inc., toll free at 800-322-2885 or collect at 212-929-5500.

YOUR VOTE IS IMPORTANT, NO MATTER HOW FEW SHARES YOU OWN. ELLIOTT URGES YOU TO SIGN, DATE, AND RETURN THE ENCLOSED GREEN PROXY FORM TODAY TO VOTE “FOR” THE ELECTION OF THE ELLIOTT NOMINEES AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                    ] TO THE BOARD AT THE 2011 ANNUAL MEETING, “FOR” THE STOCKHOLDER PROPOSAL, “FOR” THE RATIFICATION OF THE SELECTION OF INDEPENDENT ACCOUNTANTS, “FOR” THE COMPANY’S NON-BINDING RESOLUTION CONCERNING THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS, AND “FOR EVERY YEAR” ON THE COMPANY’S PROPOSAL FOR A NON-BINDING, ADVISORY VOTE ON THE FREQUENCY (EVERY ONE, TWO OR THREE YEARS) OF FUTURE ADVISORY VOTES OF STOCKHOLDERS ON THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

16

PROPOSAL NO. 1—ELECTION OF NOMINEES

We propose that the Stockholders elect Ted Antenucci, Robert J. Levenson, Allan Z. Loren and Harvey Schulweis as directors of the Company at the 2011 Annual Meeting. According to publicly available information, the Board currently consists of twelve directors, all of whom are in the same class and up for election at the 2011 Annual Meeting. If our four Nominees are elected to the Board, they will replace four of the incumbent directors: [                        ], [                    ], [                    ] and [                    ].

The Nominees, if elected at the 2011 Annual Meeting, would hold office until the 2012 Annual Meeting of Stockholders or until their respective successors have been duly elected and qualified. Each of the Nominees has consented to being named as a nominee in this proxy statement and, if elected, to serving as a director of the Company.

According to the Company’s Proxy Statement, the Board of the Company intends to nominate twelve candidates for election as directors at the 2011 Annual Meeting. This proxy statement is soliciting proxies to elect Messrs. Antenucci, Levenson, Loren and Schulweis, and to grant authority to vote for the Company’s nominees other than [                    ]. Therefore, should a Stockholder so authorize us, we will cast votes for our four Nominees and up to eight of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote have agreed to serve with any of our Nominees, if elected.

The corporate governance guidelines of the Company, which are available on the Company’s website at www.ironmountain.com, provide that determinations of independence shall be made in accordance with the criteria for independence required by the New York Stock Exchange. Except as otherwise disclosed in this proxy statement and on Annex A hereto, we believe the Nominees are independent within the meaning of the listing standards of the NYSE and the corporate governance guidelines of the Company. In addition, except as otherwise disclosed in this proxy statement and on Annex A hereto, we believe that the Nominees are independent under the heightened independence standards applicable to audit committee members under the rules of the NYSE and the SEC. No Nominee is affiliated with Elliott or any subsidiary of Elliott or has any relationship with Elliott (except as otherwise set forth in this proxy statement, including his agreement to serve as a Nominee as described in this proxy statement under “Arrangements between Elliott and the Nominees” below).

In addition, each of the Nominees understands that, if elected as a director of the Company, each Nominee would have an obligation to act in the best interests of the Company and the Stockholders in accordance with his duties as a director.

We are not seeking control of the Board at the 2011 Annual Meeting. If elected, the Nominees would be a minority of the directors and would not alone be able to adopt resolutions or otherwise cause the Board to act. However, the Nominees expect to be able to actively engage other Board members in full discussion of the issues facing the Company and resolve them together. By utilizing their respective experiences and working constructively with Board members, the Nominees believe they can effect positive change at the Company.

Information Regarding the Nominees

Information pertaining to the Nominees, including the name, age, present principal occupation, business address, and business experience for the past five years and certain other information, is set forth in the question and answer section of the proxy statement under the section entitled “Who are the nominees?”, which we urge you to read. This information has been furnished to Elliott by the Nominees. Other than as disclosed in this proxy statement, there is no arrangement or understanding between any of the Nominees and any other person(s) pursuant to which any such Nominee was or is to be selected as a director or nominee of the Company.

You should refer to the Company’s Proxy Statement and form of proxy distributed by the Company for the names, background, qualifications and other information concerning the Company’s nominees.

17

Arrangements between Elliott and the Nominees

In consideration of the Nominees’ agreement to be nominees for election to the Board, Elliott has agreed to pay each Nominee a one-time fee of $50,000 in cash. Such fee is payable in two installments as follows: (i) $25,000 upon submission by Elliott to the Secretary of the Company of a notice of nomination of candidates for election to the Board at the 2011 Annual Meeting, which fee has been paid, and (ii) $25,000 upon the earlier of (A) the mailing to the Company’s Stockholders of a Schedule 14A Definitive Proxy Statement in connection with the solicitation of proxies by Elliott in support of such Nominee’s election as a director of the Company or (B) any agreement between Elliott, on the one hand, and the Company, on the other hand, in connection with the solicitation of proxies by Elliott pursuant to which such Nominee is appointed as a director of the Company. The second installment of such fee is reimbursable to Elliott if such Nominee voluntarily withdraws from serving as a nominee, or otherwise refuses to serve as a director of the Company if so elected at the 2011 Annual Meeting.

Elliott has agreed to indemnify the Nominees against losses incurred in connection with their service as Nominees for election as directors of the Company, and in connection with the solicitation of proxies in respect thereof, to the extent that indemnification is not otherwise available, including from the Company, and to reimburse the Nominees for out-of-pocket expenses incurred in their capacity as Nominees including, without limitation, reimbursement for reasonable travel expenses. Each Nominee has executed a written consent agreeing to be a nominee for election as a director of the Company, to be named as such in this proxy statement and to serve as a director if so elected. In addition, each Nominee has executed and delivered to the Secretary of the Company the questionnaire, representations and agreements required by Section 3.3 of Article III of the Company By-laws.

Compensation of the Company’s Directors

If elected to the Board, the Nominees will not receive any form of compensation or indemnification from us for their service as directors of the Company. They will, however, receive whatever compensation the Board has established for non-employee directors of the Company unless and until the Board determines to change such compensation. The following discussion summarizes the Company’s compensation and indemnification of directors based solely on the Company’s Proxy Statement.

According to the Company’s Proxy Statement, under the Company’s Compensation Plan for Non-Employee Directors, each non-employee director receives an annual retainer fee of $52,000 as compensation for his services as a member of the Board, paid in advance in quarterly installments. In addition to the annual Board retainer, Board members are entitled to a $10,000 per year retainer for members of the Audit Committee, a $7,500 per year retainer for members of the compensation committee, and a $6,000 per year retainer for members of the finance or nominating and governance committees, in each case paid in advance in quarterly installments. In addition, the chairmen of the nominating and governance and finance committees receive an annual retainer of $8,000, the chairman of the compensation committee receives an annual retainer of $10,000, the chairman of the Audit Committee receives an annual retainer of $15,000, and the lead director receives an annual retainer of $25,000, in each case paid in advance in quarterly installments. The plan also provides for annual grants as of the first Board meeting following the Company’s annual meeting of stockholders to non-employee directors of restricted stock units of that number of whole shares of the Common Stock determined by dividing $100,000 by the Common Stock’s “fair market value” (as determined under the Company’s 2002 Stock Incentive Plan) on the date of grant. Each such restricted stock grant vests 100% on the first anniversary of the grant (or, if earlier, the Company’s annual meeting that is closest to the one year anniversary). Prior to vesting, transfer of such restricted stock grants are subject to restrictions set forth in the Company’s 2002 Stock Incentive Plan. Newly elected non-employee directors receive a pro-rated grant as of the date of their election. All directors are reimbursed for out-of-pocket expenses incurred in attending meetings of the Board or committees thereof. The Company’s Directors Deferred Compensation Plan allows non-employee directors to defer the receipt of between 5% and 100% of their retainer fees, with deferred amounts treated as invested in Common Stock. The Company’s Directors Deferred Compensation Plan also allows non-employee directors to defer some or all of their restricted stock grants, and at vesting the director’s account will be credited with a number of phantom shares equal to the number of shares that would otherwise have been delivered.

18

According to the Company’s Proxy Statement, in December 2010 the Company adopted stock ownership guidelines that require non-employee directors to achieve and maintain ownership of the Company’s Common Stock at or above a prescribed level. Directors who are also employees are subject to the Company’s executive stock ownership guidelines described in the Company’s Proxy Statement. The Company established this program to help align the long-term interests of directors with stockholders. The guidelines require directors to own and retain Common Stock of the Company, exclusive of unexercised stock options and unearned or unvested restricted stock units and performance units, having a value equal to three times the director’s annual cash retainer earned for serving on the Board. Compliance is measured by multiplying the number of shares owned at the close of business on October 1 of each year by the average closing price per share of the Company’s Common Stock, based on each trading day’s closing price as reported on the NYSE, over the 60 calendar days preceding the date of calculation. The guidelines do not limit the transfer of, or require retention of, shares of Common Stock that were outstanding as of the date of adoption of the guidelines or that are issued under any equity awards outstanding as of such date. Whenever a director does not meet the above minimum ownership threshold, such director is required to retain an amount equal to 50% of the net shares received as a result of the vesting of restricted stock units or performance units or the exercise of stock options. “Net shares” are those shares that remain after shares are sold or netted to pay withholding taxes and any purchase price. Because directors must retain a percentage of shares resulting from the vesting of restricted stock units or performance units until they achieve the minimum share ownership threshold, there is no minimum time period required to achieve the stock ownership guidelines.

The Company maintains, at its expense, a policy of insurance which insures its directors and officers. The By-laws also contain provisions that provide for indemnification of directors to the full extent permitted by, and in the manner permissible under, the Delaware General Corporation Law. The Amended and Restated Certificate of Incorporation of the Company and the By-laws contain provisions eliminating the personal liability of a director to the Company or its Stockholders for monetary damages for breach of fiduciary duty as a director, subject to some exceptions.

None of the Nominees, or any associate of any Nominee, has received any cash compensation, cash bonuses, deferred compensation, compensation pursuant to plans or other compensation, from, or in respect of, services rendered on behalf of the Company, or is subject to any arrangement described in Item 402 of Regulation S-K promulgated under the Securities Act of 1933, as amended (“Regulation S-K”).

None of the Nominees has any position or office with the Company and no occupation or employment with which the Nominees have been involved during the past five years was carried on with the Company or any corporation or organization that is a parent, subsidiary or other affiliate of the Company. None of the Nominees has ever served on the Board.

Interests of the Nominees

We expect that each of the Nominees if elected, will be (i) entitled to receive compensation customarily paid by the Company to its non-employee directors; (ii) indemnified for service as a director of the Company to the same extent indemnification is provided to the current directors of the Company; and (iii) covered by the Company’s director and officer liability insurance.

Other than as described in this proxy statement, none of the persons listed on Annex A of this proxy statement, including any Nominee, or any associate of the foregoing persons has any substantial interest, direct or indirect, by security holdings or otherwise, in any matter to be acted upon at the 2011 Annual Meeting.

The Nominees have furnished the additional information with respect to themselves located on Annex A to this proxy statement.

WE STRONGLY URGE YOU TO VOTE “FOR” THE ELECTION OF TED ANTENUCCI, ROBERT J. LEVENSON, ALLAN Z. LOREN AND HARVEY SCHULWEIS AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                    ] BY MARKING, SIGNING, DATING AND RETURNING THE ENCLOSED GREEN PROXY FORM IN THE POSTAGE PAID ENVELOPE PROVIDED TO YOU WITH THIS PROXY STATEMENT OR BY USING THE GREEN PROXY FORM TO VOTE BY TELEPHONE OR INTERNET. IF YOU HAVE SIGNED THE GREEN PROXY FORM AND NO MARKING IS MADE, YOU WILL BE DEEMED TO HAVE GIVEN A DIRECTION TO VOTE ALL THE SHARES OF COMMON STOCK REPRESENTED BY THE GREEN PROXY FORM “FOR” THE ELECTION OF TED ANTENUCCI, ROBERT J. LEVENSON, ALLAN Z. LOREN AND HARVEY SCHULWEIS AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                    ].

Please do not return any WHITE proxy card you may receive from the Company or otherwise authorize a proxy (other than on the GREEN proxy form delivered by us to you) to vote your shares of Common Stock for the Company’s nominees. If you have already submitted a WHITE proxy card that may have been sent to you by the Company or otherwise authorized a proxy to vote your shares of Common Stock for the Company’s nominees, it is not too late to change your vote.

Only your latest dated proxy will be counted.

PROPOSAL NO. 2—REPEALING CERTAIN PROVISIONS OF OR AMENDMENTS TO THE BY-LAWS ADOPTED SINCE MARCH 5, 2010

Pursuant to Article XI of the By-laws, the Board is empowered to adopt, amend or repeal the By-laws without approval by the Stockholders. Elliott believes that the Stockholders should have the opportunity to repeal any provision of or amendment to the By-laws unilaterally adopted by the Board subsequent to March 5, 2010, which is the date of the last publicly available By-laws. Adoption of this resolution could have the effect of counteracting any unilateral adoption, amendment or repeal of the By-laws by the Board that would impede the effectiveness of the proposed election of the Nominees, as applicable, negatively impact our ability to solicit and/or obtain proxies from Stockholders, countermine the will of the Stockholders expressed in those proxies or modify the Company’s corporate governance guidelines. Although we are not aware of any such provisions or amendments as of the date of this proxy statement, we are seeking your consent to vote on this proposal as a precaution against any provisions or amendments that might be adopted prior to the 2011 Annual Meeting.

For these reasons, Elliott intends to present the following resolution for a vote of the Stockholders at the 2011 Annual Meeting:

“RESOLVED, that any provision of or amendment to the By-laws adopted by the Board without the approval of the Stockholders subsequent to March 5, 2010 (purportedly the last date of reported changes) and prior to the approval of this resolution be, and they hereby are, repealed, effective as of the time this resolution is approved by the Stockholders.”

WE STRONGLY URGE YOU TO VOTE “FOR” AND TO USE THE GREEN PROXY FORM TO AUTHORIZE A PROXY TO VOTE “FOR” THE REPEALING OF ANY PROVISION OF OR AMENDMENT TO THE BY-LAWS ADOPTED BY THE BOARD SUBSEQUENT TO MARCH 5, 2010 WITHOUT THE APPROVAL OF THE STOCKHOLDERS.

20

PROPOSAL NO. 3—RATIFICATION OF THE SELECTION OF INDEPENDENT ACCOUNTANTS

As discussed in further detail in the Company’s Proxy Statement, the Company has proposed that the Stockholders ratify the Audit Committee’s selection of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ended December 31, 2011. We do not object to the ratification of the Audit Committee’s selection of Deloitte & Touche LLP and recommend that you vote “FOR” this Proposal by checking the appropriate box and signing, dating and returning the enclosed GREEN proxy form. Additional information regarding this Proposal is contained in the Company’s Proxy Statement.

PROPOSAL NO. 4—ADVISORY VOTE ON THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS

As discussed in further detail in the Company’s Proxy Statement and as required by the Dodd–Frank Wall Street Reform and Consumer Protection Act (the “Dodd–Frank Act”) enacted in July 2010, the Company has proposed that the Stockholders vote to approve, on a non-binding, advisory basis, the compensation of those of the Company’s named executive officers listed in the Summary Compensation Table appearing in the Company’s Proxy Statement. This is often referred to as a “say on pay,” and provides Stockholders with the ability to cast a vote with respect to the Company’s 2010 executive compensation programs and policies and the compensation paid to the named executive officers as disclosed in the Company’s Proxy Statement pursuant to Item 402 of Regulation S-K. This advisory vote on executive compensation is not binding on the Board; however, we understand that the Board will take into account the result of the vote when determining future executive compensation arrangements. Elliott believes that the Board’s review of the Company’s capital allocation and operational efficiency should also address strategies for more effectively aligning management compensation with stockholder value creation. However, at this time Elliott has determined not to oppose this non-binding, advisory vote. As such, we are asking stockholders to vote “FOR” the following resolution proposed by the Company:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion in the Proxy Statement for the 2011 Annual Meeting of Stockholders, is hereby APPROVED.”

We recommend that you vote “FOR” the adoption of the non-binding resolution concerning the compensation of the Company’s named executive officers by checking the appropriate box and signing, dating and returning the enclosed GREEN proxy form.

Additional information regarding this Proposal is contained in the Company’s Proxy Statement.

PROPOSAL NO. 5—ADVISORY VOTE ON THE FREQUENCY OF THE ADVISORY VOTE ON COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS

As discussed in further detail in the Company’s Proxy Statement and as further required by the Dodd—Frank Act, the Company has proposed that the Stockholders vote to recommend, on a non-binding, advisory basis, whether the non-binding, advisory stockholder vote to approve the compensation of the Company’s named executive officers (that is, a vote similar to the non-binding, advisory vote in Proposal 4 above) should occur every one, two or three years. The advisory vote as to how often the advisory vote on executive compensation should occur, often referred to as a “say when on pay”, is not binding on the Board; however, we understand that the Board will take into account the result of the vote when determining the frequency of future votes on executive compensation.

According to the Company’s Proxy Statement, the Board recommends that you vote to hold a non-binding, advisory vote on the compensation of the Company’s named executive officers annually.

21

When voting on this Proposal, you have four choices: you may elect that we hold an advisory vote on the compensation of the Company’s named executive officers every year, every two years or every three years, or you may abstain from voting. If you properly complete your GREEN proxy and fail to indicate your preference or abstention, your shares will be voted to select every one year as the frequency with which our stockholders will be asked to hold a non-binding, advisory vote on the compensation of the Company’s named executive officers.

We recommend that you vote “FOR EVERY YEAR” by checking the appropriate box and signing, dating and returning the enclosed GREEN proxy form.

Additional information regarding this Proposal is contained in the Company’s Proxy Statement.

OTHER PROPOSALS

We do not know of any other matters to be presented for approval by the Stockholders at the 2011 Annual Meeting. If, however, other matters are properly presented, the persons named in the enclosed GREEN proxy form will vote the Common Stock represented thereby in accordance with their discretion pursuant to the authority granted in the proxy.

NO APPRAISAL OR DISSENTER’S RIGHTS

Stockholders will not have rights of appraisal or similar dissenter’s rights with respect to any matters identified in this proxy statement to be acted upon at the 2011 Annual Meeting.

SOLICITATION OF PROXIES

Proxies may be solicited by mail, telephone, facsimile, telegraph, the Internet, e-mail, newspapers and other publications of general distribution and in person.

We have retained MacKenzie Partners, Inc. (“MacKenzie”) for solicitation and advisory services in connection with solicitations relating to the 2011 Annual Meeting. MacKenzie will receive a retainer of $25,000 applicable toward the final fee to be mutually agreed upon by Elliott and MacKenzie and reimbursement of reasonable out-of-pocket expenses for its services to Elliott in connection with the solicitation. Approximately 40 people may be employed by MacKenzie to solicit proxies from the Company’s stockholders for the 2011 Annual Meeting. We have agreed to indemnify MacKenzie in its capacity as solicitation agent against certain liabilities and expenses in connection with the solicitation.

Arrangements will also be made with custodians, nominees and fiduciaries for forwarding proxy solicitation materials to beneficial owners of shares of Common Stock held as of the Record Date. We will reimburse such custodians, nominees and fiduciaries for reasonable expenses incurred in connection therewith. In addition, directors, officers, members and certain other employees of Elliott and its affiliates may solicit proxies as part of their duties in the normal course of their employment without any additional compensation.

The entire expense of soliciting proxies for the 2011 Annual Meeting by us or on our behalf is being borne by us and we will not seek reimbursement of those costs from the Company. The total expenditures incurred by us to date in connection with this solicitation are approximately $[            ]. We anticipate that the total expenses that we will incur in furtherance of, or in connection with, the solicitation of proxies for the 2011 Annual Meeting will be approximately $2.7 million. The actual amount could be higher or lower depending on the facts and circumstances arising in connection with any such solicitation.

CERTAIN INFORMATION REGARDING ELLIOTT

AND THE ELLIOTT PARTICIPANTS

Annex A hereto includes information pertaining to Elliott and the Elliott Participants, including, as applicable, the name, present principal occupation or employment, business address, and certain other information with respect to Elliott and the Elliott Participants.

CERTAIN RELATIONSHIPS WITH THE COMPANY

As of March 30, 2011, Elliott Associates is the direct record owner of 1,000 shares of Common Stock and is the beneficial owner of an additional 4,189,388 shares of Common Stock, and Elliott International is the direct record owner of 1,000 shares of Common Stock and is the beneficial owner of an additional 5,486,488 shares of Common Stock, which together represents approximately 4.83% of the issued and outstanding shares of Common Stock (based on information disclosed in the Company’s 10-K regarding the number of issued and outstanding shares of Common Stock on February 10, 2011). The date of purchase, number of shares of Common Stock purchased and the price per share of Common Stock is set forth in Annex A to this proxy statement. Other than as disclosed on Annex A, Elliott, the Elliott Participants and the Nominees have not effected any transaction in securities of the Company in the past two years. The shares of Common Stock owned by Elliott were originally purchased through and held in brokerage custodian accounts which, from time to time in the ordinary course, may utilize margin borrowing in connection with purchasing, borrowing or holding of securities, and such shares of Common Stock may thereby have been, or in the future may become, subject to the terms and conditions of such margin debt and terms, together with all other securities held therein. As of the date hereof, no part of the purchase price or market value of any of the shares of Common Stock held by Elliott is represented by funds borrowed or otherwise obtained for the purpose of acquiring or holding such shares of Common Stock.

Other than as set forth in this proxy statement or on Annex A hereto, after reasonable inquiry, none of Elliott, the Elliott Participants, nor the persons listed on Annex A of this proxy statement, including the Nominees, nor any of their respective associates or majority-owned subsidiaries, is, or was within the past year, a party to any contract, arrangement or understanding with any person with respect to any of the Company’s securities including, but not limited to, joint ventures, loan or option arrangements, puts or calls, guarantees against loss or guarantees of profit, division of losses or profits, or the giving or withholding of proxies.

Other than as set forth in this proxy statement or on Annex A hereto, after reasonable inquiry, none of Elliott, the Elliott Participants, nor the persons listed on Annex A of this proxy statement, including the Nominees, nor any of their respective associates or majority-owned subsidiaries, (i) beneficially owns, directly or indirectly, or has the right to acquire, any securities of the Company or has effected any transaction in securities of the Company during the past two years; (ii) beneficially owns, directly or indirectly, or has the right to acquire, any securities of any parent or subsidiary of the Company or has effected any transaction in securities of any parent or subsidiary of the Company during the past two years; and (iii) owns any securities of the Company of record but not beneficially.

Ted Antenucci is the President and Chief Investment Officer of ProLogis, a distributor of industrial real estate, and ProLogis and the Company have existing agreements in place for the lease of real property and the provision of storage services pursuant to which the Company paid ProLogis approximately $8,100,000.00, in the aggregate, in calendar year 2010 for real property ProLogis leased to the Company, and pursuant to which ProLogis paid the Company approximately $150,000.00, in the aggregate, in calendar year 2010 for storage services provided to ProLogis by the Company. Although the determination of “independence” must ultimately be made by the Board, Elliott believes that this relationship does not involve a sufficient portion of the revenues of either the Company or ProLogis to prevent Mr. Antenucci from qualifying as “independent” within the meaning of the NYSE listing standards. Other than as set forth in this proxy statement or on Annex A hereto, (i) there have been no contracts, negotiations or transactions within the past two years, between Elliott, the Elliott Participants, nor the persons listed on Annex A of this proxy statement, including the Nominees, nor any of their

23

respective associates or majority-owned subsidiaries on the other hand, concerning any merger, consolidation, acquisition, tender offer, election of the Company’s directors, or the sale of a material amount of the Company’s assets; (ii) none of Elliott, the Elliott Participants, nor the persons listed on Annex A of this proxy statement, including the Nominees, nor any of their respective associates or majority-owned subsidiaries, have any other present or proposed material agreement, arrangement, understanding or relationship (with respect to any future employment, future transaction or otherwise) with the Company or any of its executive officers, directors, controlling persons, affiliates or subsidiaries, and (iii) none of Elliott, the Elliott Participants, nor the persons listed on Annex A of this proxy statement, including the Nominees, nor any of their respective associates or majority-owned subsidiaries or immediate family members (as applicable, and as such term is described in Item 404(a) of Regulation S-K), has had or will have a direct or indirect material interest in any transaction since the beginning of the Company’s last fiscal year or any currently proposed transactions in which the Company was or is to be a participant and the amount involved exceeds $120,000. In addition, companies under common management with Elliott are customers of the Company; however, these fees do not constitute a material expense.

Other than as set forth in this proxy statement or on Annex A hereto, there are no material proceedings to which any Nominee, or any associate of any such Nominee, is a party adverse to the Company or any of its subsidiaries or has a material interest adverse to the Company or any of its subsidiaries.

There are no family relationships (as such term is defined in Item 401(d) of Regulation S-K) between any of the Nominees or between any of the Nominees and any director or executive officer of the Company or any person nominated or chosen by the Company to become a director or executive officer.

None of the Nominees is a current or former officer of the Company and none of the Nominees was an employee of the Company during fiscal year 2010. During fiscal year 2010, no executive officer of the Company served as a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity of which any Nominee was an executive officer.

Please refer to the Company’s Proxy Statement and annual report for certain information and disclosure required by applicable law. This information and disclosure includes, among other things, securities of the Company held by the Company’s directors, nominees, management and 5% stockholders, certain biographical information on the Company’s directors and executive officers, information concerning all matters requiring the approval of stockholders, including the election of directors, information concerning executive compensation, information concerning the Company’s procedures for nominating directors, information concerning the committees of the Company’s Board and other information concerning the Company’s Board, and procedures for submitting proposals for inclusion in the Company’s Proxy Statement at the next annual meeting.

This information is contained in the Company’s public filings and the Company Stockholders should refer to the Company’s Proxy Statement and its other public filings in order to review this disclosure.

Re: Iron Mountain Incorporated

Preliminary Proxy Statement on Schedule 14A

Filed March 25, 2011 by Elliott Associates, L.P. and Elliott International, L.P.

File No. 001-13045

Dear Mr. Orlic:

The following are the responses of Elliott Associates, L.P. and Elliott International, L.P. (collectively, “Elliott”) to comments received from the Staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) in a letter from you, dated March 30, 2011 (the “Comment Letter”), with respect to Elliott’s Schedule 14A filed on March 25, 2011 relating to Iron Mountain Incorporated, a Delaware

IRS Circular 230 disclosure: To ensure compliance with requirements imposed by the IRS, we inform you that any U.S. federal tax advice contained in this document is not intended or written to be used, and cannot be used, for the purpose of (i) avoiding penalties under the Internal Revenue Code or (ii) promoting, marketing or recommending to another party any transaction or matter that is contained in this document.

David L. Orlic 2

corporation (the “Company”). The discussion below is presented in the order of the numbered comments in the Comment Letter.

General

1. Please revise the facing page of the Schedule 14A to indicate, above the heading “Name of Person(s) Filing Proxy Statement, if other than the Registrant,” that the Schedule 14A filing is being made by each of the participants.

Response:

In response to the Staff’s comment, Elliott has revised the facing page of the Schedule 14A to indicate, above the heading “Name of Person(s) Filing Proxy Statement, if other than the Registrant,” that the Schedule 14A filing is being made by each of the participants.

Proposal No. 1 – Election of Nominees, page 17

2. We note that the participants reserve the right to vote for unidentified substitute nominees. Please advise us, with a view toward revised disclosure, whether the participants are required to identify or nominate such substitute nominees in order to comply with any applicable company advance notice bylaw. In addition, please confirm for us that should the participants lawfully identify or nominate substitute nominees before the meeting, the participants will file an amended proxy statement that (1) identifies the substitute nominees, (2) discloses whether such nominees have consented to being named in the revised proxy statement and to serve if elected and (3) includes the disclosure required by Items 5(b) and 7 of Schedule 14A with respect to such nominees.

Response:

In response to the Staff’s comment, Elliott respectfully advises the Staff that Elliott has determined that, in the context of a solicitation for a minority slate, the reservation of rights and related language described in the Staff’s comment will not be necessary. As such, Elliott has deleted the language in which the participants reserve the right to vote for unidentified substitute nominees (including the “unlawful manipulation of the Company’s corporate machinery” language noted in the following comment).

3 . Please explain your reference to “unlawful manipulation of the Company’s corporate machinery” or revise your disclosure. See note to Rule 14a-9.

Response:

As noted above, Elliott has deleted the referenced language.

Solicitation of Proxies, page 22

4. You state that you may employ a variety methods to solicit proxies. Please confirm your understanding that all written soliciting materials, including any scripts to be used in soliciting proxies over the telephone, must be filed under cover of Schedule 14A. Refer to Rule 14a-6(b) and (c).

Response:

In response to the Staff’s comment, Elliott confirms their understanding that all written soliciting materials, including any scripts to be used in soliciting proxies over the telephone, must be filed under the cover of Schedule 14A on the date of first use.

Certain Additional Information, page 24

5. You refer security holders to information that will be contained in the company’s proxy statement for the annual meeting. We presume that you are relying upon Rule 14a-5(c) to refer to this information. If so, please note that we believe that reliance upon Rule 14a-5(c) before the company distributes the information to security holders would be inappropriate. Alternatively, if you disseminate your proxy statement before distribution of the company’s proxy statement, you must provide the omitted information to security holders in your own proxy statement. Please confirm your understanding in your response letter.

Response:

In response to the Staff’s comment, Elliott confirms their understanding that they cannot refer security holders to the Company’s proxy statement in reliance upon Rule 14a-5(c) if Elliott disseminates their proxy statement prior to the distribution of the Company’s proxy statement. Elliott respectfully advises the Staff that Elliott does not expect to disseminate their proxy statement prior to the distribution of the Company’s proxy statement.

Certain Relationships with the Company, page 23

6. We note the pre-existing relationship between Mr. Antenucci and the company. Please provide your analysis as to Mr. Antenucci’s independence, within the meaning of the NYSE listing standards.

Response:

In response to the Staff’s comment, Elliott respectfully advises the Staff that, pursuant to the requirements of the NYSE Listed Company Manual – Item 303A.02 (Independence Tests), it is the Company’s Board of Directors that is required to make the determination that a director qualifies as “independent” by affirmatively determining that

David L. Orlic 4

the director has no material relationship with the listed Company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company). In light of the standards set forth in the NYSE Listed Company Manual – Item 303A.02 (Independence Tests), Elliott believes that the Company’s Board of Directors would conclude that Mr. Antenucci is “independent” within the meaning of the NYSE listing standards because the pre-existing relationship between Mr. Antenucci and the Company does not conflict with any of such NYSE listing standards for “independence.” In reaching this conclusion, Elliott notes the payments made by ProLogis to the Company, and the payments from the Company to ProLogis, in each case pursuant to the pre-existing relationship described in Elliott’s Schedule 14A, do not exceed the greater of $1,000,000 or 2% of such other company’s consolidated gross revenues in any of the last three fiscal years. In light of the foregoing and in response to the Staff’s comment, Elliott has revised the language to make clear , although the determination of independence must ultimately be made by the Company’s Board of Directors, Elliott believes that Mr. Antenucci would qualify as “independent” within the meaning of the NYSE listing standards.

Form of Proxy

7. Please clearly mark the form of proxy “Preliminary Copy.” See Rule 14a-6(e)(l).

Response:

In response to the Staff’s comment, Elliott has revised the form of proxy to mark it “Preliminary Copy.”

            *             *            *            *            *             

Please note that in addition to the responses set forth above, Elliott has also made the necessary changes in the Schedule 14A to the “say on pay” disclosures, as per the Staff’s follow-up comments.

Together with this response, Elliott and the other filing persons are filing an Amendment No. 1 to amend the proxy statement in a manner consistent with the comments and responses set forth above.

In connection with responding to the comments of the Staff, Elliott and the other filing persons acknowledge that: Elliott and such other filing persons are responsible for the adequacy and accuracy of the disclosure in the filing; Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filing; and Elliott and the other filing persons may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

We appreciate the assistance the Staff has provided with its comments. If you have any questions, please do not hesitate to call Robert B. Schumer at (212) 373-3097 or Steven J. Williams at (212) 373-3257.

Very truly yours,
