Snapshots

This article applies to: Shared File Services


Snapshots are “point-in-time” versions of data stored on the share. Snapshots enable access and restoration of old versions of files. This is useful in the event of accidental deletion of a file or for reverting to an older copy of a set of files. Snapshots are the only way a file may be restored.

When a share is ordered, a snapshot schedule may be selected.

Snapshots are required if an Off-Site Disaster Recovery Copy is appropriate.
