OSS Files and Backup/Restore Utilities (T9074)
Once the pax archive exists in the Guardian file system, you use the T9074 Guardian
BACKUP command to copy the archive file to a remote tape. For information about the
BACKUP command, see the Guardian User’s Guide.
OSS Files and Backup/Restore Utilities (T9074)
OSS files should not be backed up or restored with the T9074 Backup/Restore utilities.
The T9074 Guardian BACKUP utility cannot back up OSS files in file mode, only in
volume mode. Volume mode BACKUP and T9074 volume mode RESTORE work
properly only when all of the following conditions are true:
•
All disk volumes containing OSS files can be shut down to allow the backup.
•
Related OSS catalog and data disk volumes can be down at the same time.
•
The operating system RVU on the system to be restored (the target system) is the
same as on the system being backed up (the source system).
•
The disk volumes used by OSS on the system to be restored have the same
names as the disk volumes to be used on the system to be restored.
•
The size of the each disk volume to be restored on the target system is the same
as the corresponding disk volume on the source system.
In volume mode, BACKUP backs up only what is on the volume being archived. If you
use BACKUP for OSS files, you must make sure that all filesets and all the catalog files
for those filesets you are backing up reside entirely on the single disk being archived.
To back up and restore OSS files using BACKUP and RESTORE:
1. Perform all steps described in Backing Up the OSS Environment Using a Version
of Backup/Restore on page 6-14.
2. Back up user Guardian files and related information as described in Backing Up
User Files on page 6-15.
3. Stop all filesets on the source system as described in Stopping (Unmounting) a
Fileset on page 5-13.
4. Stop all disk volumes used for OSS catalogs and OSS data files on the source
system.
5. Use the BACKUP VOLUME mode option to backup the OSS catalog disk volume
from the source system.
6. Use the BACKUP VOLUME mode option to backup the OSS data file disk volumes
from the source system.
7. Use the RESTORE VOLUME mode option to restore the OSS catalog disk volume
to the target system.
8. Use the RESTORE VOLUME mode option to restore the OSS data file disk
volumes to the target system.
