Could this be done via a file in dropbox? Just wondering, if I am using the computer in the office and the laptop at home, can I set it up so both automatically back up and access from a drop box file? Pros and cons? I'm really bad about remembering to do things like grab the flash drive before heading to the office. I've read a couple of things about hosting one computer too but not sure how that works if one computer is home and one is in the office.
