OK, I finally have enough critical and/or valuable and/or hard-to-replace data on my home network that I need to consider offsite backup. I have the free 10GB service from Dell with my recent notebook purchase, I think I'll have to give that a look. I've also read good things about Carbonite.
At the moment, however, I'm most interested in S3 Backup, currently in free beta, which uses Amazon's S3 redundant, distributed storage backend. The rates for S3 itself are pretty reasonable; rates for S3 Backup when it goes commercial remain to be seen.
Anyone have any experiences to share with online backup -- good, bad or life-changing?
