ApsaraDB RDS:CloneDBInstance

Last Updated:May 29, 2023

Restores the data of an original instance to a new instance. The new instance is called a cloned instance.

Operation Description

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

  • The original instance is in the Running state.
  • The original instance does not have ongoing migration tasks.
  • The log backup feature is enabled for the original instance to support point-in-time recovery.
  • If you want to clone the original instance by using backup sets, the original instance must have at least one backup set.
NoteApsaraDB RDS allows you to create a cloned instance by using the credentials of your RAM user. Make sure that your RAM user is granted the permissions that are required to clone an instance. For more information, see Use RAM to manage ApsaraDB RDS permissions.

Take note of the following information:

  • The new instance has the same IP address 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 that indicated by the backup set or point in time used for restoration of the original instance.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
