Abstract

A method, computer program product, and computer system for receiving, by a master controller, a request to create a read-only snapshot for an asynchronous source volume, wherein the master controller may be assigned ownership of the read-only snapshot. A peer controller may be assigned as a secondary owner of the read-only snapshot. Ownership of the peer controller as the secondary owner of the read-only snapshot may be revoked based upon a change in metadata of the read-only snapshot. The read-only snapshot may be replicated, asynchronously, from a replication source to a replication destination.
