Server Mirroring Software
For Windows and Solaris Servers

DoubleTake is fast becoming the de facto software standard for mirroring Windows and Solaris servers throughout organisations running networks of all sizes.
DoubleTake is used for both simple backup for single servers and as the basis for building complex hotsites to provide failure resistance for whole networks.

• DoubleTake allows the target machine to take over in the event of hardware or software failure in the source machine.
• DoubleTake combines data mirroring, server consolidation, disaster recovery and system maintenance.
• DoubleTake ensures that scheduled and unscheduled downtime will no longer be your concern.

How Server Mirroring Works with DoubleTake

1. Volumes and files on the source are selected for replication and then target server(s) and path(s) are selected.
2. Double-Take compares source and target files and then synchronizes the differences at a block level.
3. On-going changes to selected files are captured for replication as they occur.
4. Changes are transmitted continuously or per user-defined conditions, such as bandwidth limits or start/stop conditions.
5. Target receives and applies the changes to target volumes.
6. Target server monitors the source server and can initiate failover automatically or manually.
7. Failback releases the identity of the source allowing original source to rejoin the network.
8. The restore function returns current data back to original machine.
