看到有人用dropbox备份网站数据，所以今天也试了一下，记得以前是一个python脚本，这是用的是bash 脚本，利用dropbox的api来上传下载的，很方便，脚本的地址是Dropbox-Uploader/dropbox_uploader.sh at master · andreafabrizi/Dropbox-Uploader · GitHub ，感谢作者分享这个脚本。
可以到git下载dropbox_uploader.sh，地址为：https://github.com/andreafabrizi/Dropbox-Uploader
或者也可以直接拷贝代码，保存为dropbox_uploader.sh，注意拷贝的时候最好是复制到文本编辑器里面，如notepad++之类的
