There are a couple of options at your disposal.
If you are running Oracle 10g, look into the new Incrementally Updated Backups. This may help you shorten your backup (and recovery) times.
You can set RMAN to back up to multiple channels at the same time (disk or tape). In this way, RMAN backs up the database in parallel. If you get two channels going simultaneously, the backup should complete in roughly half the time.
Another great option is to employ hardware snapshots of your disk. This involves a third mirror of the disk drives. You tell Oracle to suspend I/O for a second. The system then unplugs the third mirror. Oracle is then instructed to resume I/O operations. This only takes seconds. Once the third mirror is unplugged, the contents of it can be copied to the backup location. Some time later, the third mirror is sync'ed up before the next backup.
