Requirements: full backup database, but the database is relatively large, if mysqldump backup mysql in a heavy load on other machines, the study api documentation Ali wrote a python script in their linux automatic backup with regular tasks.

First, install the SDK module Ali cloud rds

pip install  aliyun-python-sdk-rds

参考地址：https://help.aliyun.com/document_detail/100865.html

本地用的python环境是最新的python3.8.0
服务器上用的python环境是python3.7.4

Second, create an instance of RDS Ali cloud Python SDK interface to call the RDS CreateDBInstance

#!/usr/bin/env python
#-*- coding:utf-8 -*-
#安装：pip install  aliyun-python-sdk-rds

from aliyunsdkcore.client import AcsClient
from aliyunsdkrds.request.v20140815.CreateBackupRequest import CreateBackupRequest
from aliyunsdkcore.profile import region_provider
region_provider.modify_point('Rds', 'cn-shanghai', 'rds.aliyuncs.com')

client = AcsClient(
"<your-access-key-id>",
"<your-access-key-secret>",
"<your-region-id>"
);
 
#创建备份的RDS实例
request = CreateBackupRequest()
print(request)

Third, call CreateBackup interface to create a backup set as an example

#系统规定参数，取值：CreateBackup
request.set_action_name("CreateBackup")

#实例ID
request.set_DBInstanceId("**************")

#备份类型， Logical：逻辑备份；Physical：物理备份；Snapshot：快照备份。默认值：Physical
request.set_BackupMethod("Logical")

#备份策略，db：单库备份；instance：实例备份
request.set_BackupStrategy('db')

#数据库列表，多个数据库之间用英文逗号（,）隔开
request.set_DBName('ds_sys')

#备份方式，Auto：自动选择全量备份或增量备份；FullBackup：全量备份。默认值：Auto。
#request.set_BackupType("Auto")

response = client.do_action_with_exception(request)

参考地址：https://help.aliyun.com/document_detail/26272.html

Fourth, the full backup codes

#!/usr/bin/env python
#-*- coding:utf-8 -*-

from aliyunsdkcore.client import AcsClient
from aliyunsdkrds.request.v20140815.CreateBackupRequest import CreateBackupRequest
from aliyunsdkcore.profile import region_provider
region_provider.modify_point('Rds', 'cn-shanghai', 'rds.aliyuncs.com')

client = AcsClient(
        "**************",
        "**************",
        "cn-shanghai"
        )

#备份RDS
request = CreateBackupRequest()
#系统规定参数，取值：CreateBackup
request.set_action_name("CreateBackup")

#实例ID
request.set_DBInstanceId("**************")

#备份类型， Logical：逻辑备份；Physical：物理备份；Snapshot：快照备份。默认值：Physical
request.set_BackupMethod("Logical")

#备份策略，db：单库备份；instance：实例备份
request.set_BackupStrategy('db')

#数据库列表，多个数据库之间用英文逗号（,）隔开
request.set_DBName('ds_sys')

#备份方式，Auto：自动选择全量备份或增量备份；FullBackup：全量备份。默认值：Auto。
#request.set_BackupType("Auto")

try:
    response = client.do_action_with_exception(request)
    print(response)
except Exception as e:
    print(e)

##运行后返回结果：
b'{"RequestId":"ADC8B9B4-7CBD-484B-A646-A412825BF967","BackupJobId":"7349181"}'

View the backup tasks on the console
