Actually, I would encourage to use RMAN in conjuction with split
mirror backups. Splitted volumes can be registered as image copies
with RMAN and backed up to tape or disk storage + validated for
integrity at the same time.
With rman you would get one additional level of verification and
always up to date repository of your backups.
