solution
Zhao Yiba Notes (www.fuwuqidl.com) reminds you:
• If you have risky operations such as modifying or changing the instance or data, you must pay attention to the disaster recovery and fault tolerance capabilities of the instance to ensure data security.
• If you modify the configuration and data of instances (including but not limited to ECS, RDS), etc., it is recommended to create snapshots in advance or enable functions such as RDS log backup.
• If you have authorized or submitted security information such as login account and password on the Alibaba Cloud platform, it is recommended that you modify it in time.
