Snapshots

The Volume screen allows you to schedule and take snapshots. Think of a snapshot as a 
frozen image of a volume at the time you take the snapshot. Snapshots are typically used for 
backups, during which time the original volume continues to operate normally. As primary 
storage becomes larger, offline backups tend to become increasingly difficult because 
backup time increases beyond offline hours. Snapshots allow backups to occur without the 
need to take your systems offline.

Snapshots can also be used as temporary backups. For example, if a file on the ReadyNAS 
device becomes infected with a virus, the uninfected file can be restored from a prior 
snapshot taken before the attack. 

Taking and Scheduling Snapshots

From the Volume screen, click the Snapshot screen to display the Snapshot screen. 

Specify how often a snapshot should be taken. Snapshots can be scheduled in intervals 
from once every 4 hours to once a week. 

If you do not see a Snapshot screen on the Volume screen, you did 

not reserve any space for snapshots when you added the volume. 
The ReadyNAS ships with a snapshot reserved space of 10GB. For 
information on how to reserve space for snapshots, see
