You can use archive logs backups to recover database transactions that have been lost due to an operating system or disk failure.
You can apply the archive logs to an online backup to recover the database.
Best Practice: Create separate subclients to backup log files because they are mandatory for recovering data.
Note
-
If the archive log destination is different from the default $SAPDATA_HOME/saparch location, configure the <SID>_sSAPARCH Additional Setting to enable the CommCell Console backup and obtain the new SAPARCH location.
-
The archive log backups initiated from the CommCell Console use BRARCHIVE with the -OSC syntax and only permit one backup cycle. For more information, see the SAP note 214370.
