    How disciplined are your users? Have them create/transfer a dummy
    "/tmp/alldone" file as the last thing they do. A periodic cron job can
    check for it and if it exists, delete it and run rsync.

    Or in sshd_config, replace the sftp line with:
      Subsystem sftp /usr/libexec/sftp-server-rsync

    And create /usr/libexec/sftp-server-rsync containing:

      #! /bin/sh
      /usr/libexec/sftp-server "$@"
      touch /tmp/alldone >/dev/null 2>&1

    Modify as needed depending on where your OS puts sftp-server. You could
    have this script run the rsync directly but you'd probably get overlapping
    rsync runs and other issues; best not to try.
