Explanation: BACKUPCOPIES(backupcopies) is an optional subparameter of the CDSVERSIONBACKUP parameter specifying the number of backup copies to be cataloged and inventoried by DFSMShsm for each of the control data sets and the journal data set. For backupcopies, specify a decimal number from 1 to 9999 indicating the number of backup copies to be maintained. When the number of copies exceeds this limit, DFSMShsm removes the oldest from the catalog and if on tape, invokes the ARCTVEXT installation exit when it has been activated by the SETSYS EXITON command.
SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.
SETSYS default: None.
DFSMShsm default: See the DFSMShsm defaults for CDSVERSIONBACKUP: Specifying whether the control data sets should be backed up to multiple data sets.
