Double-Take
[QUOTE]Double-Take is a patented technology that is a step forward in high-availability and data replication, data protection and disaster recovery. Continuously capturing and replicating changes at the byte level as they occur, Double-Take replicates user selected files or entire volumes from one or more source servers to one or more target servers over standard network connections. Double-Take's disaster recovery failover capabilities allow businesses to resume rapidly after a disaster or a system outage, with or without user intervention or the time and complexities of restoring from tape.Licensing agreements with Dell, HP and IBM attest to Double-Take's best-in-class product design. These industry leaders selected Double-Take to provide data protection on NAS devices and servers with our disaster recovery capabilities.
Double-Take Benefits:
* Host-based, real-time replication without geographic limitations
Replicating changes as they occur at the byte level over any shared or private IP-based LAN, WAN or SAN, ensures that changed data can be protected nearly immediately and that an up to date replica can be made available in an instant if necessary.
* Application protection
Double-Take enables you to protect a wide range of enterprise applications such as Exchange and SQL.
* Automatic failover for uninterrupted service
In the event of a primary server outage - planned or unplanned - Double-Take allows a secondary server to stand in with the push of a button or automatically, providing disaster recovery and maximum availability to end users.
* Investment protection
Double-Take runs on your existing server and storage platforms, with no capital expenses associated with purchasing new hardware.
* Best possible protection at the lowest cost with an accelerated return on investment
Double-Take delivers extensive functionality that is typically offered only in high-end products, at a much lower entry price point. In most business critical environments Double-Take will pay for itself within months.
A host-based software replication product to achieve Microsoft Windows 2003 Server, Advanced Server and Datacenter certifications, Double-Take has established itself as a leader and is one of the only replication products that can protect everything from servers to clusters to Windows Powered NAS environments.
