I used rsync to sync files I was working on to a server >10 years ago. Only difference is that it can detect changes to file locally then update the server. To retrieve updates from the server, it relies on cron to poll the server, rather than implement some kind of push notifications. That said, it's always nice to ensure people are aware of what alternatives exist.
