I'm very paranoid about losing digital images. I'm curious how everyone else does this... Do you backup files on CD, DVD, cards, hard drives, or do you use an online service like Amazon S3? I just signed up for Amazon S3 and use Jungle Disk to sync my photo folder with Amazon's online server because it's so cheap (something like $0.15/gb stored per month). Nice thing is that I could use this to backup stuff when I'm on vacation so even if my laptop gets destroyed the stuff is still online. The downside is that it takes 8 days for my PC to upload all of my RAW photos to the internet. Suggestions for a better way?
