I do not think you need 2 Rman catalogs. Build a small database just for Rman. After the daily backup finished bring it down and do os level backup of all the environment for this small backup. You can then easily restore it in case of disk problems.
Remember: A backup is good only when you can restore from it. Test restores.

Is that really a good idea? The idea behind two instances is that they can back each other up. Is that really enough? You can lose both instances, then your backup sets are useless. We have a shared NAS, so each location uses the same set of storage. We do backup to tape as well. > > Any suggestions would be appreciated. I can handle the scripting my self.
