DescribeClusterBackups - ApsaraDB for MongoDB - Alibaba Cloud Documentation Center

Queries the backup sets of an ApsaraDB for MongoDB sharded cluster instance that uses cloud disks.

Operation description

For a sharded cluster instance that is created before October 19, 2023 and uses cloud disks, you must call the TransferClusterBackup operation to switch the instance from the shard backup mode to the cluster backup mode before you call the DescribeClusterBackups operation.

By default, cloud disk-based sharded cluster instances that are created after October 19, 2023 are in the cluster backup mode.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

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.

Operation	Access level	Resource type	Condition key	Associated operation
