I seriously doubt if anyone is actually going to make such a backup/restore util. The reason being that even if the coding were trivial it would take a very brave developer to repeatedly test the restore code on their own empeg. The chances of not trashing data while testing such a beast are fairly small.

I guess your best hope if that one of the people with "spare" empegs laying around might take the plunge...

Now if someone took the existing code for emptool, made it work over USB on Windows and wrapped a set COM classes around it then I might volunteer to do the UI side of it in VB (I would need the USB support as I would want to test it initially on my Mk1).
