Save files can be used for unattended save operations (such as backups scheduled for times when an operator will not be present to mount media volumes to receive save output). Save file can be created in the System (1) auxiliary storage pool or in a basic user (2–32) auxiliary storage pool. BRMS currently does not allow save files to be created in auxiliary storage pool devices (33–255). Please refer to the Recovering your system book for further information concerning save files and auxiliary storage pools and their use in planning your backup strategy.
