increases beyond offline hours. Snapshots allow backups to occur without the need to take your
systems offline.
Snapshots also can be used as temporary backups. For example, if a file on the NAS device
becomes infected with a virus, the uninfected file can be restored from a prior snapshot taken
before the attack.
Taking and Scheduling Snapshots
To take or schedule a snapshot:
1. Click the Snapshot tab panel on the Volume tab page. The Snapshot screen will display.
You can specify how often a snapshot should be taken. Snapshots can be scheduled in intervals
from once every 4 hours to once a week.
2. Specify the frequency and the days that you wish to schedule a snapshot:
• If you specify a start and end time of 00:00, ReadyNAS will take one snapshot at
midnight. A start time of 00:00 and an end time of 23:00 will set snapshots to be taken
between midnight and 11 pm the next day at the interval you specify. Once you save the
snapshot schedule, the time of the next snapshot is displayed. When the next snapshot is
taken, it replaces the previous one.
Note: If you do not see a Snapshot tab within your volume tab, you did not reserve
any space for snapshots when you added the volume. The ReadyNAS 2100
ships with a snapshot reserved space of 10 GB.
