Backing up all data sets in one or more storage groups

To back up all the data sets in a storage group, use the command:

BACKVOL STORAGEGROUP(sgn,...,sgn) TOTAL

The processing for backing up all the data sets in a storage group by command is the same as is explained in Phase 4: Backing up SMS-managed volumes from storage groups with the automatic backup attribute, except for the following difference:

• DFSMShsm checks the AUTO BACKUP attribute from the management class for each data set. The SMS-managed data set is eligible to be backed up if AUTO BACKUP=YES. All other values for the command backup attribute and all other attributes in the management class are ignored.
• If you specify the BACKUPDEVICECATEGORY parameter of the BACKVOL command, the data sets are backed up to the device type you specify.
• When the BACKVOL STORAGEGROUP command is issued, the volumes processed are considered to be SMS-managed.
