Double-Take

Disasters happen. Data loss doesn't have to.

Theory of Operations Double-Take

NSI™ Software's Double-Take® is a real-time data replication and failover software product. Double-Take augments your existing data protection strategy by reducing downtime and data loss, and it provides these services with minimal impact on existing network and communication resources.

The process begins by identifying the mission-critical data to be protected. The machine that holds the original copy of this data is known as the source machine. The selected data, known as the replication set, is then copied to another computer, known as the target machine. The target machine, on a local network or at a remote site, stores the copy of the critical data from the source machine. After the target has the copy of the source's data, Double-Take monitors any changes to the data contained in the replication set and sends the changes to the target machine through a process known as replication. By replicating only the file changes rather than copying an entire file, Double-Take allows you to more efficiently use resources....
