SAP Hana Log Backup

SAP Hana Log Backup

                       

                     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. 

So we can Set the default log backup location in the system.

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_5_1_876543_76543.8734647847)
