This BRARCHIVE command option backs up offline redo log files saved earlier on disk.

Input syntax: -a|-archive

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.

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

brarchive -ss -a
