This is a wrapper around rsync. Of course you could just use the
command action to call rsync yourself, but you also have to add a
fair number of boilerplate options and host facts. You still may
need to call rsync directly via `command' or `shell' depending on
your use case. The synchronize action is meant to do common things
with `rsync' easily. It does not provide access to the full power of
rsync, but does make most invocations easier to follow.

- hosts: web
remote_user: deploy
tasks:
- name: webserver update web server (--exclude-file)
synchronize: src=/home/deploy/webserver/ dest=/data/web/webserver/ rsync_opts=--delete,--exclude-from=/data/ansible/public/excludefile

實際使用：比用copy模塊速度增加很多
cat stbverify_update.yml
---
- name: handlers adserver
hosts: adservers
user: root
tasks:
- name: copy file
synchronize: src=/etc/ansible/STBVerify dest=/root/ rsync_opts=--delete
notify: stbverify handlers
handlers:
- name: stbverify handlers
shell: /bin/bash /data/sh/stbverify_update.sh
