You pointed out yourself in the comments to that answer that rsync was helpful, but that you didn't like the rude tone. The answer you accepted also agreed that you should use rsync until you edited the question to add more details. Now it's cheap and worthless?
The system seems to work. The top-voted answer is the one you accepted.
I was being generous, as rsync could be a useful suggestion to other visitors to the page, but it absolutely doesn’t answer the question that was asked. The top-voted answer, to the contrary, was edited to be genuinely helpful and an accurate answer, and deserves those upvotes. Also keep in mind that the page is getting activity because it’s linked from this discussion, so some karma changes have been triggered just now.
