Replica libraries can be configured on disks that are replicated to another disk in real-time (using either hardware replication or any third-party replication tools). Mount paths from both the primary and replicated disks can be configured as a disk library. In such a configuration, the data written by the primary MediaAgent will have read-write access, while the MediaAgent accessing the replica will have read-only access. Read-only operations (such as restores, data verification, etc.) can be performed from the replica for load balancing purposes.
