-a|-archive
This BRBACKUP command option starts BRARCHIVE at the end of a BRBACKUP run.
With this option BRARCHIVE is automatically started after the BRBACKUP backup of the data files. The offline redo log files, as well as all logs, are then copied by BRARCHIVE to the same tape(s) immediately after the backed up database files. This is also possible to disk and with BACKINT.
The main advantage of this procedure is that you only have to start or schedule one program (usually BRBACKUP). The second program is started automatically after the first program has ended. If the backup is made to tape, you can also use the tape capacity optimally.
This procedure enables both an unattended backup and an effective usage of tape capacity.
You can also specify other options for BRARCHIVE backups. If not the appropriate defaults are used. Always place the option -a (including the additional options) at the end of the BRBACKUP command line call.
a|-archive [<bra_options>]
Default value: BRBACKUP and BRARCHIVE are called separately, the backup of the data files and the offline redo log files takes place in separate backups on separate tapes.
See: Command Options for BRARCHIVE and Initialization Profile init<DBSID>.sap
Unattended online backup of a database in parallel on two tape devices followed by a startup of BRARCHIVE, in order to create two copies of the offline redo log files in parallel on the same tapes.
