several snapshots at a time. The NAS server will delete the snapshots one by one.
6. Snapshot Roll-back
Snapshot roll-back is to restore the volume to the state when the selected snapshot was taken.
Snapshot roll-back is useful if most data are lost or destroyed by virus attacks or human errors.
Snapshot roll-back is much faster than restoring from tapes. Please note that the roll-back
operation is dangerous because the whole volume will be restored to the previous state. If you
want to restore only part of the data, please simply copy them from the .snap folders to the
current file-system.
7. Snapshot Scheduling
To manage snapshot schedules, please open the administration page. Enter the “Backup →
Snapshot → Schedule” page.
To add a snapshot schedule, either click the “Add Schedule” icons next to the volume names,
or click on the “Add Schedule” button on the bottom of the page.
To delete snapshot schedules, check the check-boxes to the right and click the “Delete” icon.
To modify a snapshot schedule, click the hyperlink of the snapshot schedule in the “Schedule”
column.
There are four types of schedules – hourly, daily, weekly and monthly. Each volume can have
up to 16 schedules of any types.
