SnapServer 7.0 Administrator's Guide

Snapshots

A snapshot is a consistent, stable, point-in-time image of a Traditional RAID volume or
DynamicRAID storage pool that can be backed up independent of activity on the live
volume. Snapshots can also satisfy short-term backup situations such as recovering a file
deleted in error, or even restoring an entire filesystem, without resorting to tape. Perhaps
more importantly, snapshots can be incorporated as a central component of your backup
strategy to ensure that all data in every backup operation is internally consistent and that
no data is overlooked or skipped.
