It looks like a great idea - except - the sucking up of bandwidth to make the first backup. I'm definitely looking for a better remote backup service for my Architecture firm, for which I currently pay far too much, but my server unfortunately is Windows SBS 2003 - whose OS I truly dislike. I am forced to do this for compatibility with my Revit BIM software unfortunately, so I guess your product won't help me.
As a major bandwidth user, mainly bandwidth actually. But having the first upload for free would be a great incentive.
I think it took several days to move my data to the current system remotely which was not fun. I think its just an unavoidable problem. The severity was lessened by the service calibrating the upload to occur in the middle of the night, which really did help a lot. All of the incremental uploads also are scheduled at night, which is an obvious move.
