The FRBACKUP command enables you to create a fast replication backup version for sets of storage groups followed by a dump of each fast replication target volume. A set of storage groups is defined through the SMS construct termed 'copy pool'. Storage groups are defined to a copy pool and all of the volumes in those storage groups are backed up or dumped by the fast replication function. For a discussion of the copy pool construct, see z/OS DFSMSdfp Storage Administration.
