Backing up files couldn't be more tedious, which is probably why most of us don't bother to do it. Until it's all too late and you lose years-worth of music, movies and photos to a corrupt hard drive.

With the large data capacities that USB memory sticks offer us these days, it's not uncommon to keep essential files on such a device, only to go and drop it down a drain, or leave it in your pocket for a one-way trip to washing machine city.
