ABSTRACT:
An apparatus, system, and method for replicating a snapshot volume in a first storage system to a second storage system includes mapping information corresponding to data in the first storage system that is transferred from the first storage system to the second storage system so that a file system in the second storage system can mount the data after replication. Replication of the snapshot volume can be accomplished using a remote copy mechanism. The snapshot volume can be obtained from a primary source volume P-VOL and a differential source volume D-VOL. If the corresponding destination volumes are not known, a search is conducted to locate appropriate volumes in the second storage system. Mapping information regarding these destination volumes is utilized to enable the file system in the second storage system to mount the replicated snapshot volume.
