SAP HANA creates redo log backups automatically at regular intervals By default and in during a log backup, only the actual data of the log segments for each service with persistence is written from the log area to service-specific log backups in the file system or to a third-party backup tool.
SAP HANA automatically continues creating log backups of all the log segments that have not so far been backed up.
By default, automatic log backups are enabled in SAP HANA. You can manually disable or enable automatic log backups and for enable automatic log backups,the log mode setting must be normal.
After a system failure, you may need log backups to recover the database to the desired state.
Log Backup file format :
(log_backup) __(volume ID)_(log partition ID)_(first redo log position)_(last redo log position).(backup_ID)
Example:
A log backup name could look like this : (log_backup_1_0_1234567_1238567.1380740407446)
