That seems like a terribly inefficient way of doing things.  Creating many many
multiple backup copies.  Especially because I save quite regularly.  I could
easily end up with hundreds or thousands of backup copies.  Not what I want.  It
seems that there should be a system almost exactly like mediawiki's in which
diffs are saved, and you can see a list of versions, compare them--even across
ranges, revert them, spin through different versions with a next/previous
button.  ect.
