Re: implementing rman backup on dataguard instead of the produtcion db

I think you'll need to setup a recovery catalog for that. But, if you'd like to avoid maintaining another database just for recovery catalog there's a Metalink Doc I could refer you to

It's inside the "Oracle's Customer Knowledge Exchange" section.. & you can find other good stuff there too.. :)
