We use RMAN for a backup of a smaller (<300 GB) DB.  It doesn't require
stopping the database.

For a large (>2 TB) Oracle DB we do the BCV thing outlined below.   You
don't have to run Oracle on the media server because you do a standard
rather than an oracle backup.  (E.G. do not use RMAN - just backup the
filesystems or raw devices as if they were any other.)  We also use this
backup to do refreshes of our TEST/DEV/TRAINING environments.

You can use more RMAN streams and buffers (10 streams with 256k buffers)

You could do something like this

Put the database in backup mode
split a BCV of
Take the database out of backup mode
Mount the BCV on media server
Run a file backup of the mounted BCV
dismount BCV

Of cause every backup will be a full backup

I assume you have looked into incremental with RMAN
