Double-Take Availability ensures the availability of critical workloads. Using real-time replication and failover, you can protect data, entire servers, individual applications, virtual servers, or clusters.
You identify what you want to protect on your production server, known as the source, and replicate that to a backup server, known as the target. The target server, on a local network or at a remote site, stores a replica copy of the data from the source. Double-Take Availability monitors any changes to the source and sends the changes to the replica copy stored on the target server. By replicating only the file changes rather than copying an entire file, Double-Take Availability allows you to more efficiently use resources.
