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.
