脚本来源：http://www.andreafabrizi.it/?dropbox_uploader

脚本的原理：利用curl(字符串浏览器)模拟网页上传。好处是不需要在vps装dropbox客户端，从而降低vps内存消耗，缺点：不能像安装dropbox客户端那样同步备份。

操作步骤：

wget http://linux-bash.googlecode.com/files/uploader.sh

下载脚本

chmod 777 uploader.sh

修改权限

bash uploader.sh dropbox登录帐号 登录密码 本地文件路径 上传文件路径

执行脚本

目前只能上传单个文件，还不能上传整个文件夹。

通过上面脚本，我们很容易就可以做出备份文件数据和数据库的脚本备份到dropbox中，然后通过crontab定时每天备份。

DROPBOX_DIR="Directory in your dropbox account to store the backups, e.g. /backups"

#dropbox上存放备份文件目录

MYSQL_USER="root" #mysql数据库用户名

MYSQL_PASS="Your MySQL password" #mysql数据库密码

放到计划任务中定时备份
