老高以前写过一篇使用dropbox同步备份网站和数据库的文章，里面的内容虽说能用，但已经很过时了，今天老高给大家介绍一中更好的方式，那就是用过API备份。
新申请的Dropbox账号，默认有2G的可用空间，可以通过邀请等方式最高扩容到18G。老高直接18元入了马云家的18G账号回来改密码和邮箱?
准备
打开App Console - Dropbox，点击 Create app
- Choose an API
选 Dropbox API
- Choose the type of access you need
选 App folder ，也就是把权限控制在某一个文件夹里，比较安全，就算KEY泄露了也不会伤及无辜。
- Name your app
输入app名称，全英文，下划线可以有，不要有空格，这里创建的名称会进入到 /应用/app名称的文件夹里
最后点击创建即可！
随后进入APP设置中，在OAuth 2中找到Generated access token，点一下，复制生成的token

git clone https://github.com/andreafabrizi/Dropbox-Uploader.git
cd Dropbox-Uploader
chmod a x ./*.sh
# 第一次执行dropbox_uploader.sh时会检查主目录下面有没有 .dropbox_uploader，access token就记录在此文件里，不要忘了输入后还有一步确认
./dropbox_uploader.sh
This is the first time you run this script, please follow the instructions:
1) Open the following URL in your Browser, and log in using your account: https://www.dropbox.com/developers/apps
