Protocol

Protocol 1

If a file's timestamps have not changed since the previous backup,

    it will not copy that file across the network again.

If the file needs to be backed up again, it will (optionally) use librsync in order to save network traffic.

The server will send the client a librsync signature of the previously backed up file.

The client will use the signature to send back only the changes,

    and the server will assemble the new file by using the previous file plus the changes.

On the server side, the storage directories resemble 'hard link farms'.
