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.
