@PeterCordes that is why I recommend being careful. Myself being rather fan of bleeding edge, I quite understand why some people like long term support distros, which tend to stick to an older kernel. So sure, btrfs is maturing at a pretty good pace, but it's not an universal answer. Sure not without buts.

It's a little offtopic, but: @PeterCordes I'd be very careful recommending btrfs for production use, yet. Lately I had some data corruption issues related to btrfs and bcache on Ubuntu 14.04.

Find (or build) a statically-linked rsync binary and just run it from your home. Hopefully that won't ruin no warranty.

It is exactly what rsync does (copies only changed parts of file), but to do that, it has to read and checksum the whole file on both sides. So disk i/o is the same, but network traffic is less.

What was not working for you in the solutions ruled out? It seems that rsync would be the best bet for you...
