前辈写的一个备份脚本，一直在用，今日闲暇温故而知新一下
基本功能：定时打包网站代码文件及mysql数据库，并按周期清理历史备份。
亮点功能：可以排除网站中部分文件夹并单独对其打包（比如图片文件夹）。
配置文件如下：
#set tar www and dump db and rsync DOWWW=true DODB=true DORSYNC=true #base info WWWNAME=www.test.com SRCIP=123.123.123.123 #frequence TARSET=daily #clean frequence OLDSET=3 days ago #db setting DBNAME=testdb DBPORT=3306 DBSOCKET=/tmp/mysql.sock #tar setting TAREXTRA=--exclude=img/p/* --exclude=upload/p_img/* DEDICATEDIR=/htdocs/upload/image DEDICATETAR=upload_image
tarback.sh程序代码如下：(做了细微调整，对导出数据库进行了压缩。)
