Deleting a Pay-per-Use DB Instance or Read Replica

Scenarios

You can delete DB instances or read replicas billed in the pay-per-use mode as required on the Instance Management page to release resources. (To delete DB instances or read replicas billed in the yearly/monthly mode, you need to unsubscribe the order. For details, see Unsubscribing a Yearly/Monthly DB Instance.)

Constraints

DB instance deletion has the following constraints:

  • DB instances cannot be deleted when operations are being performed on them. They can be deleted only after the operations are completed.
  • If you delete a pay-per-use DB instance, its automated backups are also deleted and you are no longer charged for them. Manual backups are still retained and will incur additional costs.
  • If you delete a primary DB instance, its read replicas are also deleted automatically. Exercise caution when performing this operation.
  • Deleted DB instances cannot be recovered and resources are released. Exercise caution when performing this operation. If you want to retain data, create a manual backup first before deleting the DB instance.
