Managing Snapshots
By default, snapshots are enabled in Full-Server Failover. Also by
default, a snapshot is taken every 60 minutes. This may lead to
numerous snapshots on the target that you may want to manage.
You can do that by selecting Actions, Snapshot Manager. (This
option is only available when a source and target are selected and protection is enabled.)

Enable periodic snapshots—By default, periodic snapshots are enabled. Because Full-Server
Failover uses the Microsoft Volume Shadow Copy service to create snapshots, your target must
be running Windows 2003 Service Pack 1 or later. Your source and target must also be using the
NTFS file system. If you are using an earlier version of Windows or a FAT file system, this option
will not be available. If you disable snapshots, the data on the target at the time of a failure will
be used.

Snapshot Interval—By default, Full-Server Failover will take a snapshot of the target data 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 Failover
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.

Take Snapshot—If you want to take a snapshot manually (outside of the specified interval), click
Take Snapshot.
