Managing Backup Jobs
Summary of Backing Up OSS or SQL/MX Files
To start a backup job:
1. Log on to the host system where the objects to be backed up reside.
2. If you are using labeled tapes, add a CLASS TAPECATALOG DEFINE or CLASS
TAPE DEFINE. For more information,
see Using DEFINEs With Backup and Restore 2 on page 4-6
3. From a TACL prompt, start BRCOM. For information about the BRCOM run
command, see Starting BRCOM on page 4-1
4. From BRCOM, issue a BACKUP command to:
a. For a parallel backup operation two tape devices should be specified where
these are either both Tape defines, both TAPECATALOG defines, or both tape
devices. Specify a tape device for unlabeled tapes or a DEFINE for labeled
tapes.
b. Optionally, specify run options
c. Specify the OSS objects, SQL/MX objects, or a combination of both to be
backed up. If the specification is neither an OSS nor an SQL/MX object but a
Guardian name, for example . *.*.*, BRCOM will forward the backup request to
BR (T9074) instead of BR2 (T0744).
d. Optionally, specify job options
e. Optionally, specify configuration options to override the configuration options in
the BRCONFIG file
You can run multiple backup jobs simultaneously. Each job functions independently
because only read operations are performed.
Note. The other system must have both Backup and Restore 2 and any other required
software installed. For more information, see Section 2, Installing Backup and Restore 2
Note. Multiple backup jobs is not the same as parallel BACKUP where two identical tapes are
written.
