PowerStoreOS 3.5 - Secure snapshots

PowerStore enables you to generate secure snapshots. Secure snapshots provide protection from accidental or malicious deletion of backup data and are effective against ransom attacks. Unlike regular snapshots, secure snapshots cannot be manually deleted and are deleted only when they reach their expiration time.
NOTE: Secure snapshots are only supported for block snapshots that are created for volume or volume groups.

To manually generate a secure snapshot for a volume or volume group, select the Secure Snapshot option in the Create Snapshot panel. To generate secure snapshots as part of a local protection policy, create a snapshot rule and select the Secure Snapshot option in the Create Snapshot Rule panel.
