异地备份同步校验脚本

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：

#!/bin/bash
remote_host=172.16.1.111    
remote_path=/backup          
local_backup_path=/backup
local_file_path=/data
[ -d $local_backup_path ] || mkdir -p $local_backup_path 
#打包 
cd ${local_file_path} && \
tar zcf $local_backup_path/www-$(date +%F).tar.gz /data/www && \
tar zcf $local_backup_path/log-$(date +%F).tar.gz /data/log && \
find /backup -type f -name "*.tar.gz" | xargs md5sum > $local_backup_path/flag_$(date +%F) 
#同步
rsync -avz  $local_backup_path/*  $remote_host:$remote_path --passwod(省略)
#删除本地七天前
find $local_backup_path -type f -name "*.tar.gz" -mtime +7 | xargs rm -f

加入定时任务

 crontab -e
0 4 * * *  /bin/bash /root/shell/www_backup.sh &> /dev/null

服务端：

#!/bin/bash
local_backup_path=/backup
md5_file=flag_$(date +%F)
cd $local_backup_path 
if [ $? -eq 0 ];then
    if [ -e $md5_file ];then
        md5sum -c ${md5_file} >> mail.txt
        if [ $? -eq 0 ];then
            mail -s "Success ! The backup task is ok !" 7314131337@qq.com < mail.txt
        else 
            mail -s "Failed ! The backup task is failed !" 7314131337@qq.com < mail.txt        
        fi  
    else 
        ls > mail.txt
        mail -s "Failed ! The md5_file is not exists!" 7314131337@qq.com < mail.txt 
fi
