My solution using git:

    #!/bin/bash
    # run in the project root 
    git add -A   # track added files
    git commit   # local commit
    git push     # push to remote bare repository
    ssh REMOTE_HOST 'cd PROJECT_FOLDER; git pull'  # expand a working folder from the remote bare repository; usually public www folder is contained there

extra benefits: two copies of complete history for backup local and remote
