DFSMS provides a volume-level fast replication function that allows you to create a backup that is managed by DFSMShsm with minimal application outage. The fast replication function supports the FlashCopy® and SnapShot functions.
With a copy pool SMS construct, you can define a set of storage groups that DFSMShsm processes collectively for fast replication functions. For recovery purposes, you can restore the fast replication backup versions for an entire volume or copy pool, or you can recover individual data sets from the fast replication backups.
