I usually physically carry a USB drive over, set up a rsync ssh -> local-USB-drive from the one machine (`Machine 2`) that is able to connect over the network to `Machine 1`. As it is a pain to lug the drive over, I only do this rsync maybe weekly, so the rsync takes many hours (~24) to complete. Then (when I remember) I visit and I carry the USB drive back... Naturally, this slows down my work process. + +What I was hoping to do was set up git-annex with the assistant to help me.
