Wouldn't it be easier to put a back up on a floppy disk? You can fit loads onto one disk.
If you're worried in case that gets damaged, change just one date on George and do another back up onto a flash drive as written above.
Personally I back mine up onto a floppy disk and then copy that onto another disk so I always have two back ups.
When I get round to it I will pay the small cost and use Pauls internet back up.
Maybe look into doing that?
Also, you do not need to copy the entire progam, just the back up file.
