My parents have a video store where they use a computer that runs a DOS based video rental program. No windows, no nattin, save for DOS. The actual computers are hella old, and I worry about hard drive failure and them losing all their inventory and customer data........ What would be the best way to back everything up?? Keep in mind that the actual computers are very old. Very very old. I think there may be a USB connection, but without windows that's a bit superflous. Any ideas? thanks, ot.
