需求：全量备份数据库，但是数据库比较大，如果采用mysqldump在其他机器备份会大量占用mysql，所以采用全量备份，可以采用登录RDS控制台来手动点击备份，全量备份。但是太麻烦，所以研究了阿里api文档写了python脚本放在linux下用定时任务自动备份

说明：

1.每天最多备份10次

2.RDS必须支持全量备份(集群版都支持，单机版不支持)

参数说明

1.client里面AcsClient填写的参数

Shell

client = AcsClient( "", "", "")

是阿里云RAM编程管理的

region-id参考https://help.aliyun.com/document_detail/100865.html?spm=a2c4g.11186623.6.1362.1f4f38875goRqN下表1，如我是深圳就是cn-shenzhen
