Besides manual Snapshots, this feature also allows for scheduled backups. Click
on Schedule and the setup screen will appear. Check "Enable Snapshot Schedule"
and select the desired Snapshot interval. Options include Daily, Weekly, or
Monthly.
Since files and folders are limited to 16 Snapshots versions, the "Auto Delete Old
Snapshot" option allows for the removal of the oldest version automatically once
the limit is reached.
Snapshot Restore
To restore a Snapshot, simply select the desired version from list and click
"Restore Snapshot". Once the restore confirmation has been made, the selected
Snapshot will overwrite the current associated file or folder.
The other way to restore a recorded Snapshot version is manually by browsing to
the "Snapshot" folder via SAMBA (\\System_IP\snapshot). All Snapshot versions
are stored here, and you can copy or paste to restore a version manually.
