So since several us here deal in the "digital" realm, back-ups are a HUGE thing that we have to manage. I have two MAC programs that I have been using for a while. The first one is my favorite: Synchronize Pro X - its simple, does what it does, and I can just run my batch "backups" at the end of the day. http://www.qdea.com/synchronize_pro_x_intro.html Second is Pathfinder - it definitely does more, and is cheaper. http://www.cocoatech.com/pathfinder/ Still looking for good ones on PC... What do you guys use?
