Taking snapshots of the target

Make sure you have a valid source and target specified, click Configure protection from the main Full-Server Failover Manager page, and then select the Protection tab.
A snapshot is an image of data taken at a single point in time. Snapshots allow you to view files and folders as they existed at points of time in the past, so you can, for example, recover from cases where corrupted source data was replicated to the target. By default, Double-Take Availability takes periodic snapshots of the data on the target. When failover is triggered, you can use the target data at the time of failover or you can revert to a snapshot of the target data. Specify how you want to handle snapshots.

Enable periodic snapshots—By default, periodic snapshots are enabled. If you disable snapshots, the data on the target at the time of a failure will be used.
Snapshot Interval—By default, snapshots of the target data are taken every 60 minutes. If desired, increase or decrease the interval between snapshots.
Start now—If you want to start taking snapshots immediately after the full-server connection is established, select Start now.
Start at—If you want to start taking snapshots at a specific data and time, select Start at and specify the date and time parameters.
