编写shell脚本将VPS上的数据备份到Dropbox网盘的方法

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#!/usr/bin/env bash # # Dropbox Uploader # # Copyright (C) 2010-2014 Andrea Fabrizi <andrea.fabrizi@gmail.com> # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
