cat /root/ansible_copy/hosts

[backup]
10.1.1.1  serverid=1001     ansible_ssh_user=backup_user ansible_ssh_port=22 

通过 mode 控制同步方向
mode=push 默认值。从『控制机』到『目标机』
mode=pull 从『目标机』到『控制机』

ansible -i /root/ansible_copy/hosts backup -m synchronize -a 'mode=push src=/tmp/svr_01/backup/ dest=/tmp/svr_02/backup/'

拉取 pull

ansible -i /root/ansible_copy/hosts backup -m synchronize -a 'mode=pull src=/tmp/svr_01/backup/ dest=/tmp/svr_02/backup/'

delegate_to 授权

需要注意的是，使用 delegate_to 授权机进行 synchronize 。需要保证授权机能密钥访问远程机。因为 delegate_to 时，使用的帐户权限是授权机的，而非 ansible host 的。

Notes

rsync 必须状态本机与目标机.
For the synchronize module, the “local host” is 同步的发起方, and the “destination host” is 同步的接收方.
可以使用 delegate_to 改变 “local host” . 该功能可以实现在两台远程机器上同步，或者在一台远程机器上执行两个目录的同步。
synchronize src 所使用的 用户 和 权限 是在本机发起 Ansible 任务的用户的权限（或者是使用 delegate_to 时，授权机上的 remote_user）
synchronize dest 所使用的 用户 和 权限 是目标机上的 remote_user 的用户权限；或者为使用 become=yes 时的 become_user 的权限。
In 2.0.0.0 a bug in the synchronize module made become occur on the “local host”. This was fixed in 2.0.1.
目前， synchronize 被限制使用无密码 sudo 提权。这是因为通过 rsync 连接到远程机器，且 rsync 并未提供任何使用 sudo 方式的接口。
同步策略决定了目前只有少部分连接 (ssh, paramiko, local, and docker) 方式支持 synchronize。 Note that the connection for these must not need a password as rsync itself is making the connection and rsync does not provide us a way to pass a password to the connection.
Expect that dest=~/x will be ~<remote_user>/x even if using sudo.
Inspect the verbose output to validate the destination user/host/path are what was expected.
To exclude files and directories from being synchronized, you may add .rsync-filter files to the source directory.
rsync daemon must be up and running with correct permission when using rsync protocol in source or destination path.
The synchronize module forces --delay-updates to avoid leaving a destination in a broken in-between state if the underlying rsync process encounters an error. Those synchronizing large numbers of files that are willing to trade safety for performance should call rsync directly.
