11.17 Backing Up and Restoring the System Disk
6. If your system disk contained more data than one tape could store, you
receive the following messages and prompt:
%BACKUP-I-RESUME, Resuming operation on volume 2
%BACKUP-I-READYREAD, Mount volume 2 on MUA0: for reading
Enter "YES" when ready.
If you do not receive these messages, see step 7. If you do receive these
messages, perform the following steps:
a. Remove the backup tape from the drive.
b. Insert the next backup tape into the drive.
c. When you are ready to continue, enter Y (for YES) and press Return.
d. The procedure displays the following message:
%BACKUP-I-STARTVERIFY, starting verification pass
Each time the procedure displays a mount request, follow steps a through
c.
7. If you are using standalone BACKUP, when the restore is finished the system
displays the following message:
%BACKUP-I-PROCDONE, Operation completed. Processing finished at 19-MAY-2000
15:30. If you do not want to perform another standalone BACKUP operation,
use the console to halt the system.
If you do want to perform another standalone BACKUP operation,
ensure the standalone application volume is online and ready.
Enter "YES" to continue:
Continue with step 9.
8. If you are using the menu system, the DCL prompt appears after the restore
is finished. Log out and choose the shutdown option from the menu.
9. Remove the last backup tape from the drive.
10. Halt the system.
11. Reboot the system.
12. Store the backup tapes in a safe place.
11.17.5 Backing Up the System Disk to a Disk
To eliminate disk fragmentation, perform a disk-to-disk image backup without
using the /SAVE_SET qualifier. This creates a functionally equivalent copy of the
entire system disk, on which files are stored contiguously.
Note
This procedure initializes the output disk, effectively erasing the files on
the disk.
