Chapter 7 Snapshots A snapshot is a consistent, stable, point-in-time image of a volume 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 file system, 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. Note Some Snap Servers require a license before Snapshots can be enabled. The Snapshot options will be hidden if the server is not licensed for them. To license Snapshots, go to the SnapExtensions screen and click the License Required link next to Snapshots.
