Snapshots provide a simple and effective method for protecting local data. Snapshots provide immutable point in time copies of data and the ability to instantly recover if there is data corruption or deletion. Because PowerStore snapshots are 100% read-only and cannot be modified or manipulated, they are ideal for recovering instantly from ransomware attacks.

Snapshot rules can be created as part of a protection policy to define a schedule for snapshot creation, access, and retention. Only users with an Administrator or Storage Administrator role can administer snapshot policies. When used with Dell AppSync, application-consistent snapshots can automatically be created and scheduled.
