Preventing Unwanted Physical Backups

If a backup job template file specifies a logical backup format (the default option), CA VM:Backup determines whether it should perform a CMS or physical backup of each minidisk in the job.

If all minidisks to be backed up are assumed to be CMS minidisks, specify CMS as the backup format. Then, if CA VM:Backup encounters any non-CMS minidisks (such as unformatted minidisks), it indicates in the job report that an invalid minidisk was encountered and not backed up. If a logical backup is specified as the format for the backup, CA VM:Backup performs a physical backup of any non-CMS minidisk it encounters.

Specifying CMS also prevents CA VM:Backup from backing up full pack minidisks accidentally when they were not specifically excluded in an exclusion file.
