Hehe, I had such a device long ago. It was ok-ish for making infrequent backups, but too burdensome to use regularly, since you had to bring in the videoplayer (it was a huge device, zoomer! :D), untangle and attach the wires. And then the reading/writing speed was slow, so it took a few hours to fully use a single videotape. Also a simple video tape wasn't very reliable medium, and, though ArVid had some inbuilt redundancy, still it was possible you won't read the data after a few months/years, so you had to backup the backup to be extra sure... But it was a solution to a problem, nonetheless. Very cheap and alternative-less for even twice or more money it cost. Real salvation even back then, so I'm happy and thankful they made it.
