Like that Corvus hard disk I picked up, which has a VCR backup option. I vaguely remember some similar backup systems in the Amiga age too, but as very few owned hard disks, a backup was of limited use (what is the point of backing up floppies to tape?).
I believe a VCR has a longer start-up phase than an audio tape recorder, so if you're going to use it to load individual programs, you may need more space between each file and it will be more cumbersome to use. But as Kent said, it is nice to experiment.
