You can carry out
For log backups, we recommend that you activate automatic log backup (
Activating and Deactivating the Automatic Log Backup). However, you can also make your log backups interactively to file.For SAP applications, the backup function of the Database Manager can be set to the optimum automated timetable by using the DBA Planning Calendar of the Computing Center Management System (CCMS). Log files on the backups performed are generated in the SAP system and these give you an accurate picture of what happened during the backups.
