Mirroring only protects you against drive failures and not human error.And I disagree with that. Mirroring *definitely* makes both reads and writes go faster, due to parallelism.Hmm. Don't ^ these.Backups are always necessary, mirroring is optional but speeds up recovery from hardware failure *only*. Sometimes, you can't backup (it doesn't make sense, it's too big, ..) and thus, yes, you also *need* mirroring (not just to speed up things). But it will not help you in case of human error, as Stan said.
Note that I didn't mention human error; probably should have snipped out that part.
