I thought about this, and it would perhaps help, but it would bloat the
archive location if used repeatedly, perhaps every minute so you have a
recent version.  It also might not work on server shutdown because there
might not be time to do the archive.  I think we are going to need a
solution to archive the current file in a different way.
