为什么选用COS

腾讯有一个东西叫做：COS，也就是对象存储，其实就和以前使用的七牛存储差不多

不过使用COS作为备份还是有优点的，首先康康的网站架设在腾讯云上，只要COS建立的是同一地区的，那么备份时自动使用内网访问，速度快啊！

而且就算VPS不是在腾讯云上，对于COS的免费版本来说也是可以不花钱的，因为入流量是免费的，不区分内外网啊，就算出流量也有每月10G的免费额度，完全够用了！

创建COS

创建完成后，左侧点击“密钥管理”，根据自己的Bucket分配域名获取相关密钥

安装Python2.7

由于官方sdk运行环境为Python 2.7，所以这里需要自行安装Python 2.7环境

更改脚本

使用下面脚本，将自己的配置信息填进去，地域标识那里，不清楚的请看这里：https://cloud.tencent.com/document/product/436/6224#.E9.80.82.E7.94.A8.E4.BA.8E-json-api，看其中“适用于 JSON API”的说明
