can superduper back up external drives?

[arckachihc]

I'm looking for software that at a set interval (say every 2 days) backs up an external drive onto another drive to prevent data loss. Can SD do this?

Yes, you can set SuperDuper! to back up on a schedule, every M, W, F, for example. We only back up Mac-native (that is, HFS+/Mac OS Extended) drives, though, and won't work with Windows formatted drives, if that's what you have.
