I've been working through various recovery scenarios. The SAP HANA Administration Guide at SAP Press has been a huge help in understanding the details so a big thank you to Lars and Richard for creating the book.
I'm having trouble finding details on how the recovery process would work in the following two scenarios. Any details or suggestions would be appreciated.
1) If I have made full database backups and transaction log backups (let’s assume the last one was at 9am) . I have a data volume failure at 9:15am but the log volume is still available. I understand that the system will replay the log segment when it can if the “most recent state” option was selected.
What if I have the above scenario (log segment is still intact but not yet backed up). I want to load the backups onto a new location. How do I capture the log records between the last log backup and the point of failure? Will the log backup run if the index server data volumes are damaged or unavailable?
2) How do you recover off backup if the backup catalog is removed or corrupted? The recovery process appears to be extremely dependent on the backup catalog file and I am curious how we can handle a scenario when that is not available.
Thanks
