I can't imagine why you would use atime instead of ctime for backups.
Oh, wow, I just realized that I was confusing the atime with the A
(archive) bit from DOS... It would be more likely the mtime that would
be used by a backup program. But you still don't want the atime getting
reset arbitrarily. Anyway, Chris confirmed that scrub doesn't change
any of that.
