I disagree. 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.
