This BRARCHIVE command option verifies the backup after the offline redo log files were saved.

You can use this option to make sure that the backup is readable and complete. Once the archiving phase is complete, all the saved files are read from the volume (for example, tape) in sequence, decompressed (when compress = yes was used), read by the check program, and compared with their originals. When archiving to disk, verification is performed immediately after archiving the individual offline redo log files.

If the option -s, -sc, -ss or -cs is used, the file contents are compared in binary form. If the option -sd, -scd, -ssd or -cds is used, the sizes of the archived files are determined and checked.

  1. -w|-verify [only_conf|use_rmv|first_rmv|only_rmv]
End of the code.

Default value: no checks

Possible values:

  • only_conf: BRARCHIVE calls the external backup utility only to confirm that the backup is known, not to verify the data.

  • use_rmv: restores and then verifies the successfully backed-up files using RMAN

  • first_rmv: verifies the original offline redo log files using RMAN before the backup starts

  • only_rmv: verifies the original offline redo log files using RMAN without starting a backup

Note that verification approximately doubles the archiving time required.

For security reasons, we recommend using this option at least once within the volume expiration period for your archiving with -s, -sc, -ss or -cs. It enables you to detect any possible hardware problems and undertake the appropriate measures.
