Being the paranoid person that I am I purchased an external hard drive that simply plugs into my PC and I back up everything of any value on it and disconnect it when not in use either completely if I am off on vacation and it goes into the safe or simply by switching it off. I can also access it on my laptop if I need to. The small price you pay for the hardware is nothing compared to the loss of all the pics and information that it takes years to collect that can never be replaced.
