-a|-archive 

Input syntax:
-a|-archive [[<SID>],<log_nr>|[<SID>],<log_nr1>-<log_nr2>|
<log_nr_list>]

Default value: BRARCHIVE saves all offline redo log files to tape, which have not already been saved to tape. Both the copies saved directly to tape as well as those written to tape via a disk backup are taken into account. At the most two copies can be written to tape.

Specifying the offline redo log files to be backed up via the entry <log_nr> is only sensible in exceptional cases.

The option -a|-archive can only be used in combination with the following BRARCHIVE-options: brarchive -s| -sc| -ss .

A copy of the offline redo log files which were copied to disk in a previous backup is created in parallel on each of two different tapes:

 brarchive -ss -a
