I'm trying to figure out a way to get more granular reporting on my Oracle database backups. I can see in my daily license report that the capacity of my "Oracle Database" backups is growing -- the problem is I can't tell exactly which database is causing the issue. Our DBA's back up their databases using RMAN scripts - which use multiple threads to run their backups - so in my reports, I see multiple jobs from the same client backing up the same database simultaneously. I could add them all up manually, but I really don't want to have to do that for EACH database (we have lots of them!)
Is there an easier way to get an overall view of the backup size (current as well as historical, or some kind of growth report) of each individual database without having to add them up manually?
