"Personal" online storage seems to be the way (Score 1)

Regarding your question on Carbonite: "Carbonite does not currently back up files that are larger than 2GB in size, removable hard drives (e.g., USB drives) or mapped network drives." "Carbonite will back up all the supported files on your hard drive whether you have 1GB, 10GB or more. As a practical matter, the speed of today's DSL and cable Internet services will make it very slow to back up more than, say, 40-50GB of data. Our Terms of Use will allow us to deny service to abusers." Given those terms, it's going to be tough to get past 100GB or so. I will have to consider getting a dedicated server at a hosting facility or do some kind of peer-sharing with friends and/or fellow photographers.
