It shouldn't do that, Walter.

You can make multiple backups with SuperDuper!, as explained in the Introduction to the User's Guide, to cover this case. But as I said, you should be able to do a reinstall of Snow Leopard, which is the equivalent of an archive-and-install. They just renamed it to make it clearer to most users.

I'm sorry that you're frustrated, but it seems that "My Living Desktop" should have a way to restore its own functionality without requiring this kind of extreme action... note that you could try the OS reinstall over the backup to see if you get the result you want, too, without affecting your regular drive...
