Zusammenfassung:The present disclosure relates to applying a data deduplication layer on top of an asynchronous remote replication protocol. In embodiments, a remote replication group including one or more of a storage array's logical unit numbers (LUNs) can be established. Further, at a remote system, -the remote replication group can be remotely replicated on a per LUN basis using a deduplication fingerprint of each LUN's data tracks corresponding to the remote replication group.
