Using Backup Media to Recover from a System Failure

Restoring Files from Partial Backup Tapes

Use the RESTORE command to copy system ﬁles, user ﬁles, and the ﬁle system

directoryfrom your STORE backups to disk.

To restore system and user ﬁles from your most recent backups, perform the following

steps:

1. First gather all the units of backup media from your most recent backup.

2. Mount the backup(s) on the backup drive(s) and bring the drive(s) online.

3. After a system failure, only LDEV 1 is available as the system volume set. You must use

the VOLUTIL program in order to initialize your other volume sets, if you have not done

so already. This can be done with the following set of commands:

:VOLUTIL

volutil: NEWVOL

volumesetname:membername

LDEV=

The

volumesetname

for the system volume set is MPEXL_SYSTEM_VOLUME_SET. Issue the

NEWVOL command for each member of the volume set. For more detailed instructions,

see the Volume Management Reference Manual.

4. Issue the following FILE and RESTORE commands to copy the ﬁles from the backup

media.

:FILE T;DEV=TAPE

:RESTORE *T;@.@.@;KEEP;OLDDATE;DIRECTORY

5. Monitor the console for tape requests.

6. Mount additional backup media when necessary until you have copied all ﬁles from all

backups.
