Restoring From a Physical Backup

If your data was backed up in physical format, CA VM:Backup displays ** Non-CMS ** next to the virtual address on the file selection screen and the Select Version of Minidisk or Directory to Restore screen.

A minidisk is backed up in physical format if changes are being made to it while CA VM:Backup tries to back it up, if your system administrator requested a physical backup of your minidisk, or if it is not a CMS-format minidisk. If you usually see file names on the file selection screen, contact your system administrator before restoring data with this descriptor. If you are not sure how to restore the data, contact your CA VM:Backup system administrator.

When you restore data backed up in a physical format, you can restore the entire minidisk or individual cylinders or tracks. You cannot view or select the individual files. Although the backup data contains all the files on the minidisk, the data is backed up by track for count-key-data (CKD) devices or in groups of 32 blocks of 512 bytes for fixed-block-architecture (FBA) devices instead of CMS file format.
