If you're using the achive logger and keeping all your archived redo logs, you could get away with once a week (although I would be nervous doing so).
If you are NOT using the archive logger, then absolutely no way; never; do this at your peril. Oracle constantly updates the redo log id's in all its tablespaces. get two backups with different redo ids and no redo logs and recovery is next to impossible and data will certainly be lost (I know from bitter experience)
