That depends on how you set up your backup jobs. VM:Backup will (as you said) back up Linux/390 DASD in physical format - track images or FBA block-group images. If you specify a full backup, everything gets backed up. If you sepecify an incremental backup, things get more complicated. With "file-level detail" catalogs and hash-change-detection, you can specify that only the changed tracks/block-groups get backed up. See the VM:Backup System Programmer's Reference "Backing Up Non-CMS Minidisks" section for details. Ross Patterson Computer Associates
