I use GoodSync (website name is same), for all of my sync between Laptop, NAS, computers and FTP with my websites. There is a free copy, but for the price ($30, $10? for a second), you can sync anything. I like it because you maintain your directory and file structure, you are not required to put everything in a common folder. Worth a look.
