Restores an original ApsaraDB for RDS instance to a new instance, which is called a clone instance.

Before you call this operation, make sure that the following requirements are met:

  • The original instance is in the Running state.
  • All migration tasks on the original instance are completed or stopped.
  • The original instance has log backup enabled to support point-in-time recovery (PITR).
  • If you want to clone the original instance by using a data backup file, the instance has at least one data backup file.
    Note ApsaraDB for RDS allows you to create a clone instance by using the credentials of your RAM user. Make sure that your RAM user is granted the required permissions. For more information, see Use RAM to manage ApsaraDB for RDS permissions.

Take note of the following:

  • The new instance has the same whitelist, SQL Explorer (SQL Audit), alert threshold, backup, and parameter settings as the original instance.
  • The data and account information of the new instance is the same as the information indicated by the data backup file or binary log file of the original instance.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
