备份web与nfs服务器

所有服务器的备份目录都为 /backup

要备份的系统配置文件包括但不限于如下（没有目录则手动创建）：

定时任务服务的配置文件： /var/spool/cron/root

开机自启动的配置文件： /etc/rc.local

日常脚本的目录： /server/scripts

Web服务器目录： /var/www/html

Web服务器日志： /app/logs

Web服务器本地保留打包后7天的备份数据即可

备份服务器 backup 上保留最近7天的备份数据，同时保留6个月内每周一的所有数据副本

备份服务器上按照备份服务器上的内网IP为目录保存备份，备份的文件按照时间名字保存

每天00:00进行备份，早上8:00 把备份成功或失败的结果信息发送至系统管理员邮箱
