交易系统备份方案

公司的交易系统bs架构，通过http方式访问备份数据库。开发公司不肯合作的态度，所以每一次必须人工的去登陆网站是手动备份。
每天安排6次备份，这种对于一个程序开发者来讲的话真是一种痛苦和侮辱。

今天空下来就用python开始编写自动备份方案：
1.http自动登录
2.wget断点下载
3.7zip压缩
4.网盘 everbox的同步到服务器

与http server的交互信息用wireshark抓包分析，还蛮灵光的

python代码：

1 # -*- coding:utf-8 -*-
2 # auto backup system database
3 # 自动登录，http下载，压缩之后通过网盘同步到服务器
