Info

If DB can reach admin mode: The loss of data includes the period as of the last savepoint, which you can determine using the detailed information for this backup under 'Last Save Point' (Database Studio -> Administration -> Backup -> Details or DBMCLI command backup_history_list). We always recommend that you back up the most recent log information from the online log volume one more time, even if parts of the log volume may be defective. The backup process then saves all intact log pages until the first page error occurs. If DB can not reach admin mode: In this case, the loss of data includes the period as of the last log backup. Additional useful info: If you are using the mirroring log mode (mirrored volumes) and one of the two log volumes has failed, refer to SAP note 1177052: Mirrored log: Recovery of deficient log volume
