Risks Associated with Unmanaged Snapshots

Unmanaged snapshots can reduce the amount of reported free space available in an array group, which can limit the available space for other volumes. In worse case scenarios, unmanaged snapshots can increase array space usage beyond optimal threshold levels and can impact performance. Is is therefore recommended that you periodically review and delete any unmanaged snapshots that are no longer required in accordance with your Restore Point Objectives (RPO).
