SKIPABPRIMARY and NOSKIPABPRIMARY: Specifying whether to skip automatic backup of primary volumes

Explanation: SKIPABPRIMARY | NOSKIPABPRIMARY are mutually exclusive, optional parameters specifying whether or not to back up data sets on DFSMShsm-managed volumes with:
  • The primary volume attribute of automatic backup, specified with the PRIMARY(AUTOBACKUP) parameter of the ADDVOL command
  • The storage group attribute for automatic backup, specified with the AUTOBACKUP=YES for the storage group.
SKIPABPRIMARY specifies that during automatic backup, DFSMShsm skips the backup of DFSMShsm-managed volumes with:
  • The primary volume attribute of automatic backup
  • The storage group attribute of AUTOBACKUP=YES
Therefore, all users must back up their data sets on the DFSMShsm-managed volumes. DFSMShsm, however, backs up data sets while the data sets are on migration volumes that migrated from a volume with the primary volume attribute of automatic backup or from a storage group with the attribute of AUTOBACKUP=YES.

NOSKIPABPRIMARY specifies that during automatic backup, DFSMShsm backs up primary volumes with the automatic backup attribute and storage groups with the attribute of AUTOBACKUP=YES.

SMS relationship: Parameter differs in meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.

SETSYS default: None.

DFSMShsm default: If you do not specify either parameter on any SETSYS command, the DFSMShsm default is NOSKIPABPRIMARY.
