Abstract
Recovery of a primary image is facilitated by using consistent snapshots on a primary storage array and consistent snapshots on a secondary storage array to avoid the need to transmit entire secondary replicas of storage objects from the secondary storage array to the primary storage array. Consistent snaps of the primary replicas are generated by the primary storage array. Consistent snaps of the secondary replicas are generated by the secondary storage array. The primary image is recovered by linking consistent snaps on the primary storage array to primary staging volumes, linking consistent snaps on the secondary storage array to secondary staging volumes, synchronizing the primary and secondary staging volumes, and migrating host IO traffic to the synchronized staging volumes.
