Backing Up OSS Files to Other Expand Nodes
You can perform a remote backup of OSS files indirectly by using the pax utility and writing the
backup archive to a directory within the Guardian file system (a directory within/G), where the
archive file is a Guardian file. For more information on creating a backup archive in a /G directory,
see “Creating a pax Backup of OSS Files in the Guardian File System” (page 190).
NOTE: You cannot restore an OSS file that is larger than approximately 2 gigabytes to a system
running an RVU that does not include support for OSS large files.
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.
Backup and Restore 2 Product and Restricted-Access Filesets
To allow the Backup and Restore 2 product to access files in a restricted-access fileset, all of the
executable files for the product must have the appropriate file privileges. The initfilepriv
command sets the correct file privileges for each of the Backup and Restore 2 product files. You
must be a member of the Safeguard SECURITY-PRV-ADMINISTRATOR (SPA) group to use the
initfilepriv command. In this example, the Backup and Restore 2 product files are in the
$system.sys22 subvolume:
$ initfilepriv /G/system/sys22
For more information about restricted-access filesets and file privileges, see “Using Restricted-Access
Filesets and File Privileges” (page 228). For more information about the initfilepriv command,
see the initfilepriv(1) reference page, either online or in the Open System Services Shell
and Utilities Reference Manual.
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” (page 185).
2. Back up user Guardian files and related information as described in “Backing Up User Files”
(page 186).
3. Stop all filesets on the source system as described in “Stopping (Unmounting) a Fileset”
(page 151).
