I have stuff saved on my computer, too, and lots of printouts so I can flip through them easily. Unfortunately I haven't got them in binders like I planned, but they are lined up on a shelf with quilt patterns and books.
My friend says she saves all her embroidery designs and so forth on an external hard drive. When there is a hurricane and we have to evacuate like we have the last couple of years, she just takes that with her. I think she also has pictures saved on the hard drive. My husband uses an online backup since he needs to be sure he doesn't lose anything for business. He is happy with it and talked about adding it for my computer, but so far we haven't done that. :D
