After you define a copy pool, you must define a copy pool backup storage group. A copy pool backup storage group contains the target volumes for fast replication backup versions. For information on how to use ISMF to define a copy pool backup storage group, see Defining storage groups.
Each copy pool backup storage group must be associated with a pool storage group. You must specify the name of the copy pool backup storage group on the Pool Storage Group Define/Alter panel.
You can use the BACKUPSTORAGEGROUP parameter to override the copy pool backup storage group with an alternate storage group. You can specify this optional keyword with the EXECUTE and PREPARE keywords of the FRBACKUP command for DFSMShsm: Requesting a Fast Replication Backup or Dump Version. For more information, see z/OS DFSMShsm Storage Administration.
