Dean - Do both, if you can. As cheap as the 250GB SATA drives are, put two in a mirror in the system and use one to do the nightly backup to. Mirroring gets you protection against drive failure, and the nightly backup gets you a 24 hour window of protection against deleted data.
Alan was right about rsync: it's a great way to do nightly backups, you can do incremental rsync and speed things up dramatically over a full nightly dump.
