自动备份VPS数据的shell脚本

使用说明，将其保存为backup.sh,并为其添加执行权限
chmod +x /root/backup.sh

其中ftp账户密码自己配置。
代码如下：

#!/bin/bash
#为backup.sh添加执行权限chmod +x /root/backup.sh
#添加脚本至crontab(自动启动程序)执行命令crontab -e，添加每天0点10分启动代码
#10 00 * * * /root/backup.sh
 
#===========配置区开始==============
BACKUP_DATA_TEMP="/home/backup"
DB_USR="数据库用户名"
DB_PWD="数据库密码"
FTP_HOST="FTP主机名"
FTP_USR="FTP用户名"
FTP_PWD="FTP密码"
ZIP_PWD="压缩包密码"

#数据库文件位置
DB_PATH="/home/mysql_data"

#网站数据文件位置
WEB_PATH="/home/ftp/1520"

#其它要备份的文件夹
OTHER_PATH="/home/lum_safe_files"

#按周清理，设为0则按天清理
ROUND_WEEK="1"
#===========配置区结束==============
