BRCOM RESTORE Command Processing

The PRIVSOARFOPEN file privilege is set on the BR2DS, BR2ODS, BR2DMA,
and BR2ODMA executable files. For information on how to set the file privileges on
executable files, see Configuring Backup and Restore 2 on page 3-1.
The backed up files can be restored to a restricted-access or unrestricted target fileset.
Restoring to the Unrestricted Fileset
A super ID can restore to an unrestricted fileset irrespective of the file permissions set
on the unrestricted fileset.
Members of the SECURITY-OSS-ADMINISTRATOR security group are treated as
normal users.
BRCOM RESTORE Command Processing
When you issue a BRCOM RESTORE command:
1. The DMA process validates the RESTORE request and the tape utilization
parameters. If you backed up the files using a TAPECATALOG define, this includes
validating file security within DSM/TC.
2. Backup and Restore 2 uses the BRIC file during the restore process to determine
which tapes need to be mounted into the tape drive. If you do not specify the
DIRECTORY job option, DMA restores the BRIC file from tape when the restore
job begins. If you are restoring objects from a backup job that spans multiple tapes,
the BRIC file determines which tape contains each object being restored:

If you specify to restore all the objects in a backup job that spans tapes,
Backup and Restore 2 starts with the first tape and then restores all objects
from succeeding tapes.

If you specify multiple restore specifications but not all objects are being
restored, the DMA might request and use tapes out of sequential order.

If you do not mount the last tape of a backup job on unlabeled tapes, Backup
and Restore 2 requests tapes until the last tape or tapes containing the BRIC
file are found.
Note.

Only the members of the SECURITY-PRV-ADMINISTRATOR security group can set or
remove the fileset restrictions.

The restricted-access fileset attribute and the SECURITY-PRV-ADMINISTRATOR security
group are supported only on systems running J06.11 and later J-series RVUs and H06.22
and later H-series RVUs.
Note. If members of the SECURITY-OSS-ADMINISTRATOR group restore a backup image to
an unrestricted fileset, the restoration might fail because the SECURITY-OSS-
ADMINISTRATOR group members are treated as normal users in an unrestricted fileset and
the restoration is subject to file permissions set on the unrestricted access fileset.
