Log files that contain information and messages

Edit online

Data Protection for SAP processes are recorded in log files. Information about backup operations can be used to determine which backup should be used to restore your data.

Data Protection for SAP records data in two log files that can be used during troubleshooting:
  • backup.log
  • backint.log
Both log files can be opened through the SAP HANA Studio menu options Open Perspectives > Administration Console.

The backup.log log file records the start and finish of backup and restore operations. The success or failure of the operations is also recorded. All SAP HANA node details in a scale-out environment are stored in a single backup.log log file.

The backint.log log file contains the IBM Storage Protect™ for ERP data for all database and redo log file backup and restore operations that complete successfully or fail.

SAP HANA scale-out systems

In a scale-out environment, there can be many SAP HANA nodes with the databases spread among many hosts. The logs from all hosts are combined into a single backint.log for the entire instance.

When you are analyzing the logs for errors, or you want to examine some transactions, you can find the relevant host by going to the Parameters section of the backint.log file.
