Hard drives provide near-online backup, but only a single full iteration. You can do incrementals to DVD or CD-RW or tape, and keep many iterations handy, which is far more reliable.

If you use dump/restore you can do iterative backups to a spare HD as well...

Sure. But a single spare HD is a single point of failure. Having one tape per week or per month going back 10 or 100 tapes gives much more redundancy....
