And why on earth would you want to use any alternative to rman? RMAN *is* the method for managing backup and restore of the database.

Do you look for an alternative to creating/using indexes to optimize query performance?

Do you look for an alternative to using a battery and electric motor to start your car?

RMAN brings so much automation and intelligence to the process that it is a total waste of time to try to roll your own. If you are looking to do the work that would be necessary to come up with a viable alternative to rman, then you have *waaay* too much time on your hands and your shop is already overstaffed on DBA's.
