Specifying which storage group has automatic backup performed

The AUTO BACKUP attribute of the storage group specifies whether DFSMShsm performs automatic incremental backup on the volumes assigned to the storage group. For the example system, the AUTO BACKUP attribute for all storage groups is AUTO BACKUP = Y.

As with the space management example, backup for any of the storage groups is not limited to a single host. However, should you want to limit the processing to a single host, you can use the BACKUP SYSTEM/SYSPLEX NAME attribute in the same way as the MIGRATE SYSTEM/SYSPLEX NAME attribute was used. A sysplex name can also be used as the BACKUP SYSTEM/SYSPLEX NAME.

Figure 1 shows the backup attributes added to the storage groups for the example system.
