Is there a way to link two computers to a backup drive without creating a "network"?

I have two computers. I have a backup drive that I want to have both computers linked to. Is there a way to do it without creating a network?

Yes, you can use a USB switch (not a USB hub, that's different). Assuming the backup device is USB, this will work, although only one of your computers can use the device at a time. I think you also have to manually switch which computer can use the device using a button or hotkey.

If this is impractical to you, go the network route, setting up a network is really pretty easy.
