Fairly new to SBM, but am enjoying it so far. I was just wondering what everyone does for back-up & storage. I'm doing 12x12 pages at the highest resolution, and my computer is really slowing down. Also, if I try to do more than 5 pages in an album it just completely freezes.

Do you use external hard drives? Back up to CD? How do you keep them organized by event?
Thanks in advance for any advice.
