I guess it depends on how much you trust Amazon or Google with your stuff. I created my own music archive/backup directory through my Web hosting service (DreamHost). Since I'm already paying them like $7/month for hosting GaragePunk.com and a few other domains, I figured this was the best way for me to do it, and I just access the directory via FTP (which never crashes, haha). I've done the same thing with all of our family photos, creating a separate directory for Photo Archives. It's always backed up, and with unlimited storage space, I'll never run out of room. Problem solved.
