Fred,
What I've heard described is that if you have a very large site, you could
configure two RMAN backup systems (and catalogs). RMAN A backs up half your
Oracle databases and RMAN B's catalog. RMAN B backs up the other half of
your Oracle databases and RMAN A's catalog. When the tool you own is a
hammer, all the world looks like a nail. So of course the RMAN developers
are going to suggest using RMAN to backup RMAN's catalog, after all, if they
recommended another method, that might imply that RMAN wasn't adequate for
all your backup needs.
On a practical level, I think you need to evaluate what is right for
your site. What will provide the protection you need with the level of
effort in setting it up and maintaining it corresponding to the need. If you
are responsible for 200 databases, your approach may be different than if
you are only responsible for 2.
