This kind of thing can be quite tricky.  If you want it to be
invisible to the users, it will be a huge amount of work.  In most
situations, you're better off just having a spare machine ready to
take over and letting the users know that the backup won't be fully up
to date.

Beyond that, you really have to identify the vulnerability scenarios
you're trying to ameliorate.
