Anyone know a small and lightweight program to monitor a directory for changes in the background and file sync these to a remote server?

A little bit like Dropbox, but I wan't it to be able to specify exactly what directories and where that specific directory should sync to via SCP/FTP/REST API or anything like that to a remote system.

It should run in the background 24/7, so not a "Windows Commander" type of application that monitors and syncs when it is open.

Windows and Linux support required.

I use BitTorrent Sync from resilio: https://www.resilio.com/individuals/ Free version works very well, has clients for Windows, Mac, Linux, iOS, Android and even Network Attached Storages.


Syncthing would be good option as it is free, secure and open source. It supports Windows, Mac, Linux and Android.
