Exhibit 99.1

Double-Take Software, Inc. Provides Preliminary Third Quarter Financial Results

SOUTHBOROUGH, Mass.--(BUSINESS WIRE)--Double-Take Software, Inc. (NASDAQ: DBTK), today announced preliminary results for the third quarter of 2008. Based on preliminary financial data, the Company now expects third quarter revenue to be in the range of $23.8 million to $24.0 million, compared to its previous guidance of $25.7 million to $26.3 million. The Company expects net income per diluted share to be $0.10 to $0.11 per share and adjusted, non-GAAP net income per diluted share to be $0.14 to $0.15 per share. Previous guidance for adjusted, non-GAAP net income per diluted share was $0.15 to $0.16 per share.

“In the latter part of September customers delayed closings on a number of expected deals in both Europe and in the American regions. This apparent push of business is atypical for Double-Take and has not been experienced to such extent previously in the US market,” said Dean Goodermote, Chairman and CEO of Double-Take Software, Inc. “The deals in question generally were our larger opportunities, and were across multiple verticals; though we did experience specific issues with some financial institutions and companies in the Houston area affected by hurricane Ike. "While the expected revenue miss may not require us to pre release, management believes that it is important to provide this new information as timely as possible to the investment community," concluded Goodermote.

The Company will release final results for the third quarter on October 28, 2008 and will host a conference call to discuss its final financial results on Tuesday, October 28, 2008 at 4:30 p.m. EDT.

The Company calculates adjusted non-GAAP income per share by excluding the effects of non-cash stock based compensation, resulting from the application of SFAS 123R, from Operating Expenses.

Non-GAAP Financial Measures

Double-Take Software, Inc. has provided in this press release adjusted non-GAAP income per share financial information that has not been prepared in accordance with generally accepted accounting principles, or GAAP. Double-Take Software, Inc. uses this non-GAAP financial measure internally in analyzing its financial results and believes it is useful to investors as a supplement to, but not as a substitute for, GAAP measures in evaluating the Company’s operational performance. Double-Take Software, Inc. believes that the use of this non-GAAP financial measure provides an additional tool for investors to use in evaluating operating results and trends, and in comparing its financial results with other companies in Double-Take Software, Inc.’s industry, many of which present similar non-GAAP financial measures to investors. The adjusted non-GAAP income per share presented above excludes non-cash stock-based compensation charges of approximately $.04 per share from our results and exclude the effect of these charges in the related diluted share count.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures.
