Linux下web服务器备份恢复脚本

linux下的Web服务器备份恢复脚本,经测试centos和freebsd下都可以用只不过要修改脚本当中的变量TAR为系统的tar命令路径，脚本如下

#!/bin/sh   
cat < /dev/null 2>&1   
                echo -e "$COLOR_GREEN$TIME $b备份成功！请继续选择其他操作$COLOR_BACK"  
                echo "$TIME $b备份成功！$TIME" >> /var/log/web_back.log   
            else    
                echo -e "$COLOR_RED需要备份站点不存在，请重新输入:$COLOR_BACK"  
                read d   
                if [ -d $WEB_DIR/$d ];then  
                    cd $WEB_DIR  
                    $TAR $TAR_BACK $BACK_DIR/"$d"_back_`date +%Y%m%d`.tar.gz $d/ > /dev/null 2>&1   
                    echo -e "$COLOR_GREEN$TIME $d备份成功！请继续选择其他操作$COLOR_BACK"  
                    echo "$TIME $d备份成功！$TIME" >> /var/log/web_back.log   
                else    
                    echo -e "$COLOR_RED备份站点名输入出错两次，退出当前备份选择！$COLOR_BACK"
