We had done a few tests in the area of Backup and Restore of HANA System using both the Local and Backint based backups
One of our tests failed for a point in time restore of the HANA system that should have used both Data and the log backups to restore based on the time we chose
Here is the error we found
Further checks revealed the Data restore was successful and the recovery failed during the log segment restore
At this time the log_mode was set to NORMAL on the destination HANA System
We suspected the issue could be either
1. Corrupted log
2. Or the log_mode setting
Due to lack of time we tried changing the Point of restore to a different time than before and also used log_mode= OVERWRITE
This time the recovery completed and we were left with an open question if log_mode could have been responsible or a corrupted log
No further tests could be carried on due to time constraints of the project so this open question could not be validated
To validate this point I did another point in time recovery test for a different HANA system using backint tool leaving the log_mode in NORMAL state and the recovery worked
We have asked the Backint service provider if there are any specific settings for the log_mode for doing a point in time recovery and waiting for a feedback
I am posting this to share the results of my tests and seeking feedback if there is any documentation from SAP that confirms the log_mode setting while doing a point in time recovery
