Results When you create a protection policy that includes a replication rule, the policy is automatically replicated to the remote system and assigned to destination resources created by the policy. The replicated policy and associated rules names are identical to the policy and rules on the source system with the name of the remote system appended at the end. Changes made to the original policy or included rules, are replicated to the remote system to maintain synchronization. After a replication failover, the replicated policy becomes active on the destination system. The replicated policies and rules are managed by the system and are not displayed in the destination system policy and rules tables. However, you can see the rules details in the Protection tab of the replicating volumes or volume groups, by hovering over the replicated policy name. For protection policies that are assigned to metro volumes, an identical read-only policy is created on the remote system and can be viewed on the Protection Policies window of the remote system PowerStore Manager. Modify a protection policy You can modify a protection policy by adding and removing snapshot and replication rules. About this task NOTE: Changing the settings of a protection policy applies the new settings to all objects to which the protection policy is assigned. If you need to change the protection policy for one resource, it is recommended to create a new protection policy, and assign it to that resource instead. You cannot change the replication destination on a replication rule used in protection policies which are assigned to one or more storage resources. To reconfigure replication to a different remote system, unassign the protection policy and assign a new one with a different replication rule. Unassigning a protection policy with a replication rule will delete the associated replication session and assigning a new protection policy will create a new one, which requires a full synchronization to the new destination. Steps 1. Select Protection > Protection Policies. 2. Select the check box next to the relevant policy and click Modify. 3. In the Properties slide-out panel, you can modify the following parameters: ● Policy name ● Selected snapshot rules ● Selected replication rules 4. Click Apply. Assign a protection policy Assign a protection policy to one or more storage resources to apply the snapshot and replication rules included in the policy to the storage resource. The protection policy automatically performs snapshot operations and replication 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 anytime. When you assign a new protection policy that contains a replication rule to the storage resource, a complete initial synchronization is required. You can assign protection policy to a storage resource during the resource creation or at a later stage. For block storage protection, you can assign protection policies containing snapshot and/or replication rules to volumes and volume groups. With file 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 will be applied to all file systems on the NAS sever and snapshot rules (if such exist) will be ignored. You can assign a protection policy to a file system only if it includes a snapshot rule. The snapshot rule will be applied to the file system and a replication rule (if such exists) will be ignored.
