What Is the RDS DB Instance Storage Configuration?
Updated at: Jul 07, 2021 GMT+08:00
RDS uses Elastic Volume Service (EVS) disks for storage. For details about EVS disks, see Elastic Volume Service Product Introduction.
The RDS backup data is stored in OBS and does not occupy the database storage space. For details on the RDS DB instance storage configuration, see the Object Storage Service User Guide.
