You've already got another copy of your RMAN repository in your control file in addition to the one in the RMAN catalog, so I'm not sure why you'd want to go to such an extent to have a 3rd copy of your RMAN repositories. Why not just backup your RMAN catalog database just like the rest of your databases, but using only its own controlfile as the repository?
