备份脚本：
[root@client ~]# crontab -l 0 * * * * /bin/sh /root/backup_rsync.sh [root@client ~]#
参数说明：
-a 相当于-rlptgoD，-r是递归 -l是链接文件，意思是拷贝链接文件；-p表示保持文件原有权限；-t保持文件原有时间；-g保持文件原有用户组；-o 保持文件原有属主；-D 相当于块设备文件；
-u, –update 仅仅进行更新，也就是跳过所有已经存在于DST，并且文件时间晚于要备份的文件。(不覆盖更新的文件)
-z 传输时压缩；
-P 传输进度；
-v 传输时的进度等信息，和-P有点关系，自己试试。
–delete 表示客户端的数据要与服务器端完全一致，如果客户端目录里有服务器上不存在的文件，则删除。
