Hello, I have BTSync set up to do a one way sync of several large backup files from one server to another. Server A - Server where files are created / modified and need to be replicated. Server B - QNAP NAS device that should store the backed up files. Everything was working great for about a week. Files on Server A would be manipulated and modified and the changes correctly sent over to server B as exptected. It seems now that Server B is sending stuff back to Server A and it's not clear why. See: http://puu.sh/c1xcs/6312cf99d6.png The backup file ending in 618 does not actually exist on Server A anymore. It was deleted automatically by the application that makes the backups. Yet sync is downloading it from Server B, the opposite of what a one-way sync should be doing. The file is large (450 GB), so it's going to be a bit for it to finish synching. I just dont know why its's synching it at all.
