Backing up a drive is an entirely different process done for entirely different reasons. All I'm asking for is the same thing any word processor has.

BiaB may be some of the buggiest software I've used on a regular basis, but it's actually pretty good about pulling itself out of (not responding) situations, so that may be why folks don't feel the need for backups. But BiaB does lock up on occasion. And this does result in lost work. You may not see this is a priority, but I do, and a rather high one. Because BiaB has no backup feature I now get to go back over a file and spend an hour or more redoing what I lost. Infuriating. There's no excuse for not having this feature -- or at least an equivalent to what Cakewalk does when it crashes. It asks the user if they want a backup copy created. And if the users sez "yes" the backup is created in the same directory that the original file is located. Plus, the backup is up to date to the second the program crashed. This is a workable alternative.
