但在轻量云的使用过程中发现，快照功能不支持自动进行备份，需要手动进行备份，作为懒人的话非常不方便，而且备份嘛一般习惯在凌晨夜深人静的时候悄悄操作，所以，就有了这个脚本。
需要注意的是，轻量云只支持免费保存两个快照镜像，大于2个估计是要收费的，所以轻量云的快照不要超过两个。
那么我这个脚本也会删除较早的一个，保存一个并生成一个快照这样迭代。
首先还是安装腾讯云API的库
pip install -i https://mirrors.tencent.com/pypi/simple/ --upgrade tencentcloud-sdk-python
之后保存代码另存为一个.py文件，另外注意修改最下面你的相关腾讯云参数为自己的，因为是通过API进行操作，所以这个脚本不需要放在你的轻量云上面，脚本可以放到任意地方进行操作，但需要注意不要让你的腾讯云API信息泄露。或自行下载https://github.com/fungjcode/python_tools。
