Unsupported Tape Format
Unsupported Tape Format
BRCOM and the BACKUP and RESTORE utilities (T9074) support different tape
formats. Therefore, you cannot mix Enscribe and SQL/MP files on the same tape with
the OSS and SQL/MX files.
Unsupported Restore Operation
You cannot use a previous product version update (PVU) of Backup and Restore 2 to
restore a backup created using a later PVU. For example, you cannot use the AAB
PVU to restore files that were backed up with the AAC PVU. However, you can use a
later PVU to restore files backed up on any previous PVU of Backup and Restore 2.
Changed or Unsupported Commands
BRCOM supports the same commands as the BACKUP and RESTORE utilities
(T9074) with the exception of Parallel BACKUP and BACKCOPY. BACKCOPY is
supported only on systems running H06.06 and later H-series RVUs. Parallel BACKUP
is supported only on systems running H06.05 and later H-series RVUs.
When using RVUs other than the ones mentioned above, to back up two copies of the
data, use the BRCOM BACKUP command twice rather than using the BACKCOPY or
parallel BACKUP. To back up three copies of the data, use the BRCOM BACKUP
command three times.
These command features are supported in the BACKUP and RESTORE utilities
(T9074) but are not supported by Backup and Restore 2. In some cases, the same
function is provided in another way:

Backup and Restore 2 does not support explicit wild cards for any object except
CATALOG *.
However, Backup and Restore 2 does support implicit wild cards for objects. For
example, if you specify a SQL/MX schema, all objects subordinate to that schema
are backed up or restored unless you exclude them. If you specify the OSS
directory /usr/home, all objects in that directory and all its subdirectories are
backed up or restored unless you exclude them. If you specify the OSS directory /,
the entire OSS file system is backed up or restored.

Backup and Restore 2 does not support excluding a specific file or directory by
name.

You can exclude an OSS file based on its creation time, last open time, or
modification time.
Note. Wild cards are supported for job IDs.
