Dell PowerStore Protecting Your Data

Assign a protection policy

Assign a protection policy to one or more storage resources to apply the snapshot, replication, and remote backup rules in the policy to the storage resources. The protection policy automatically performs snapshot operations, replication, and remote backup based on the specified parameters.

If a protection policy that meets your data protection requirements is available, you can assign it to a storage resource at any time.

You can assign a protection policy to a storage resource during the resource creation or at a later stage.

For block storage protection:

• Assign protection policies containing snapshot, replication, and/or remote backup rules to volumes and volume groups.
• When you assign a new protection policy that contains a replication rule to the storage resource, a complete initial synchronization is required.
• With remote backup, assigning a policy that includes a remote backup rule to a volume or a volume group, automatically creates a remote backup session in Idle state.
• If a policy that includes a remote backup rule is assigned to a resource that does not support remote backup, the rule is ignored.
• With metro volumes, you can assign only protection policies that include snapshot rules. A policy that includes a replication rule cannot be assigned to a metro volume.

For file storage protection:

• PowerStore supports local protection (snapshots) at the file system level and remote protection (replication) at the NAS server level.
• You can assign a protection policy to a NAS server only if it includes a replication rule. The replication rule is applied to all file systems on the NAS server and snapshot rules (if such exist) are ignored.
• You can assign a protection policy to a file system only if it includes a snapshot rule. The snapshot rule is applied to the file system and a replication rule (if such exists) is ignored.
• You can assign different protection policies to a NAS server and to the file systems it includes.
