Mark is a bit frustrated that he can't automatically backup videos using Carbonite. Leo says that is by design, because videos use up a lot of bandwidth. It would kill his internet access for days, weeks, or even months just to backup videos. It's fine for documents and images, but he really needs to do the math in order to do video and then determine when he wants to do it. Leo says that's why he recommends backing up to a hard drive that he can take off site.
