You should be able to do this over ssh. Install openssh-server on your tablet, and you can connect to the tablet and mount it as a drive. You may need extra software to do this from Windows (I use Linux, which has the capability built in, so I don't have any recommendations). After that, any software that can sync folders will do the rest.

Conduit would probably be better, but that package is out of date and missing dependancies, and I can't find a new one.
