When backing up data physically, CA VM:Backup backs up data by track for CKD devices or in groups of 32 512-byte blocks for FBA devices. CA VM:Backup automatically performs a physical backup if a minidisk is not formatted for CMS, but you can also request that CA VM:Backup back up data physically.
Data backed up using this format is device-dependent when it is restored. If you restore a CKD device, the target volume must be the same device class and type as the source volume; for example, you must restore a 3380 device to a 3380 device. If restoring an FBA device, the target volume must be an FBA device.
