RHEV 3.0 / 3.1 support for Netbackup backup ?

I have done some search on RH's KB / Google but only thing I have managed to find is this for RHEV 2.2:

http://www.redhat.com/resourcelibrary/reference-architectures/RHEV-2-2-Backup-and-Recovery-using-Symantec-NetBackup

Is there a nice way for Netbackup to backup RHEV ? Or some doc about with step by step how-to like the one in obove link just for RHEV 3.0 or 3.1 (when it become Final / GA).
