I hava a MacPro 10.9.1 with four bays of storage including one Seagate 4TB formatted in OS X but without an installed OS. I have a static IP for the server and desire to use the 4TB HDD as a storage backup device. I can ssh to the server but am not sure how to setup an ftp client (Transmit, Fetch, Cyberduck) to backup/sync to an internal HDD on the server which is separate from the OS drive. For illustration, connect at the imaginary location of ssh email@example.com where mark is the user on the server and 188.8.131.52 is my static IP. I can provide real data if needed.
