Double-Take® Software Launches a New Version of Double-Take® for Linux Enhancing Availability of Critical Linux-based IT Workloads

Version Offers Industry`s First Software-based Block- and Byte-Level Replication
SOUTHBOROUGH, Mass.--(Business Wire)--
Double-Take Software (NASDAQ: DBTK) today announced the availability of
Double-Take for Linux version 4.5 which enables customers to easily protect the
availability of Linux-based IT workloads without requiring specialized or
proprietary hardware and storage-based availability solutions. This new version
of Double-Take for Linux offers extended distribution support for Novell® SUSE®
Linux Enterprise Server 10 and CentOS 4 and 5. It also adds disk block-level
replication to its current file byte-level capabilities, making Double-Take for
Linux the only software-based product to provide both byte-level and block-level
replication.

It is important for customers to have the flexibility of using either block or
byte -level replication depending on the application and workload in need of
protection and Double-Take Software is the only software-based replication
provider that enables this. This new version of Double-Take for Linux allows
customers to protect data residing on additional file systems and within
applications like Oracle which leverage raw disk modes. Double-Take for Linux
also provides users with support for ReiserFS, an additional option for
protection of block-based data, and support for and the ability to run Xen®
para-virtualized kernels. Double-Take Software will add support for the recently
released Novell SLES 11 in its next Double-Take for Linux service pack, due out
in June.

"Double-Take Software aims to support our customers independent of their vendor
relationships, and we`re pleased to broaden our reach to Novell SLES 10 and
CentOS 4 and 5," said Bob Roudebush, director of solutions engineering at
Double-Take Software. "This new version also strengthens Double-Take Software`s
position within the market by offering two types of data replication and
providing customers disaster recovery solutions that are flexible and easy to
use."
