The following operations are supported on snapshots for all storage resource types unless otherwise noted. These operations can be completed using PowerStore Manager, PowerStore CLI, or REST API. Usually, the snapshot operations below for volumes, volume groups, file systems, thin clones, and virtual machines are the same. Differences in behavior are explained.
Starting in PowerStoreOS 3.5, the secure snapshot setting is available. This setting is optional when creating a snapshot for volumes and volume groups. When the secure snapshot setting is enabled, the snapshot is protected from deletion until the retention period expires. This provides a cost-effective line of defense against ransom attacks and accidental deletion of snapshots, volumes, or volume groups.
