More about git-ftp:

If you use Git and you need to upload your files to an FTP server, Git-ftp can save you some time and bandwidth by uploading only those files that changed since the last upload.

It keeps track of the uploaded files by storing the commit id in a log file on the server. It uses Git to determine which local files have changed.

You can easily deploy another branch or go back in the Git history to upload an older version.
