Actually, when I mentioned revision control via a repository, I was
thinking about when you mentioned that you would loose some data if
you had to restore from backup.

Another idea (to prevent you from loosing data) is to overwrite your
documents and other files on the backup with what you have today. Then
you could restore from the backup and all your files would still be
there. Of course, it would take a few hours, and it brings with it the
possibility that you might bring the Mathematica startup problem to
the presently working copy.
