Dear experts,
we are moving towards integrating RMAN in BRBACKUP for all the systems in our environment.
We have also decided to take Full (level 0) backups twice per week and cumulative backups
each evening.
I would like to ask on 2 details in case I would need to restore such a cumulative backup:
I. How is the restore exactly done ? This is how I currently picture it for myself:
1. The full backup would need to be restored first.
2. Apply the offline redologs that were generated during this full level 0 backup
3. Then restore the last available cumulative backup
4. In the end, apply the offline redollogs generated during this cumulative backup
Or perhaps step 2. is not necessary ?
II. I have come across the following document:
I am a bit confused by the following statement on page 6:
In contrast to the BRRESTORE restore process without RMAN, which requires a closed database, restoring with RMAN requires the database to be mounted
What exactly does that mean ? Do I imagine the restore process wrongly, as I depicted it in I. ??? Kindly advise and let me know
in a clear and understandable form, not in the common fuzzy SAP language :-) Many thanks in advance!
