Sorry guys, I'm naive to all of this as you may have noticed from my previous comment. I was thinking to back up onto 2 externals as was suggested to me I would have to attach one external, then disconnect it and attach the second one. But then I think I just read Ihno saying there is a way to attach 2 externals to your computer at the same time? Just wondering because i am stuck with just a one-computer "network" lol.
