实现功能：
将客户端服务器A的每天的数据（/www,/log）本地打包，并且配置定时脚本每天同步到服务端服务器上，在服务器上对备份的数据进行校验，将结果发送到管理员邮箱。
客户端：
1 #!/bin/bash 2 remote_host=172.16.1.111 3 remote_path=/backup 4 local_backup_path=/backup 5 local_file_path=/data 6 [ -d $local_backup_path ] || mkdir -p $local_backup_path 7 #打包 8 cd ${local_file_path} && 9 tar zcf $local_backup_path/www-$(date +%F).tar.gz /data/www && 10 tar zcf $local_backup_path/log-$(date +%F).tar.gz /data/log && 11 find /backup -type f -name "*.tar.gz" | xargs md5sum > $local_backup_path/flag_$(date +%F) 12 #同步 13 rsync -avz $local_backup_path/* $remote_host:$remote_path --passwod(省略) 14 #删除本地七天前 15 find $local_backup_path -type f -name "*.tar.gz" -mtime +7 | xargs rm -f
加入定时任务

服务端：
