Another timesaver with RMAN is to skip READ ONLY tablespaces. It is rare for a 10TB+ database to update many of...
those terabytes of data on a regular basis. Place the data that is not getting updated in tablespaces separate from the data that does get updated. Then, make the non-updated tablespace READ ONLY. Back it up with RMAN. Since the tablespace is READ ONLY, you do not need to back it up again. You can have RMAN perform a full backup of your database, but skip the READ ONLY tablespaces. You may find that you only need to back up 1TB on a regular basis and your other 9TB were last backed up nine months ago!
Using RMAN is vital to backing up a VLDB. I would suggest going to http://tahiti.oracle.com and reading the backup and recovery guides for your version.
