One option is a Cold backup
-Shut down your db instance for a time each night; the tape backup
software will back up all the database files in a consistent state
A cold backup once a week, combined with backing up archive logs each night, is also a pretty reasonable strategy, and not all that complicated to implement. Just make sure someone's educated themselves on (and clearly documented) disaster recovery procedures involving cold backups and archive logs.
You'll also want to read about RMAN. No need for backup outages when you're using RMAN.
I won't bother saying anything specific about it; you should likely just go straight to the Oracle Docs and start reading. But RMAN is pretty much the de facto backup and recovery tool for Oracle dbs.
Here's a couple of links.
