We noticed that our rman backup process for PROD database is not working properly.
PROD is a 8 TB size database having two bigfile tablespaces each having more than 2 TB datafile.
PROD is a 11gR1 (11.1.0.7) RAC database with ASM storage.
We are taking weekly incremental level 0 backup for entire database and level 1 backup every day.
As per v$session_longops, the approx completion time for the two tablespaces is 5 days.
We can use "SECTION SIZE" parameter to take rman backup for bigfile tablespaces and exclude them from the level 0 backup.
However, in this case our level 0 backup wont include the two bigfile tablespaces and the daily level 1 backup will not include them.
Will you pls advise us on how to take backup in this scenario.
we have only 4TB of LUN allocated for backup and have to keep 7 days of backup on disk.
Thanks in advance !
