Within PowerStore, snapshots are used by asynchronous replication to provide point-in-time images as the source of Recovery Point Objective (RPO) based updates to the destination. These snapshots are used to maintain the common base images between the source and replicated resource across systems. Snapshots that are created and maintained by replication are not visible to the user within PowerStore Manager.
When replication is configured on a volume, volume group, or their thin clones, any snapshots that are created on the source resource are automatically replicated to the destination system during the next RPO-based update. These snapshots can be viewed on the destination, but user operations such as the restore operation are not allowed at the destination for a replicated object. If access to destination snapshots is required, thin clones can be leveraged to provide host access to the data. Snapshot replication is not supported on file resources. For more information, see the white paper Dell PowerStore: Replication Technologies on the PowerStore Info Hub.
