Oracle RMAN backup - making oracle server as media server

Dear All, 

We would like to speed up our RMAN backups and I was wondering if the following would work:

(Environment: windows 2008 enterprise R2 x64, netbackup 7.5)

I'd like to install media server edition of Netbackup to Oracle server so it can do the backups to DataDomain 990 faster.

what else will be required? is my theory correct? 

thanks
