I usually use Dropbox or Ubuntu One to sync my different devices. Now I need to sync contents of a folder with a folder on a Linux server. Note that I may make change files on both sides. The first one is my laptop and the second is a computing server that I have ssh access to (regular user but not root access).
You can install Dropbox for linux
You will be able to specify the folder you want to sync the account ect.
