rsync上机实战考试题：
某公司里有一台Web服务器，里面的数据很重要，但是如果硬盘坏了，数据就会丢失，现在领导要求你把数据在其他机器上做一个周期性定时备份。要求如下：
每天晚上00点整在Web服务器A(web01 )上打包备份网站程序目录并通过rsync命令推送到服务器B(backup)上备份保留
（备份思路可以是先在本地按日期打包，然后再利用rsync推到备份服务器上）。
具体要求如下：
1)Web服务器A和备份服务器B的备份目录必须都为/backup。
2)Web服务器站点目录假定为(/var/www/html)。
3)Web服务器本地仅保留7天内的备份。
4)备份服务器上每周六的数据都保留，其他备份仅保留180天备份。
5)备份服务器上检查备份结果是否正常，并将每天的备份结果发给管理员信箱。
