Deleting a DB Instance


This section guides you on how to delete a DB instance no longer used to release resources. You can delete the following types of DB instances:

  • Cluster instance
  • Replica set instance
  • After you delete an instance, all nodes in the instance are also deleted.
  • After you delete the DB instance, all data in it and all automated backups are automatically deleted and cannot be restored. Exercise caution when performing this operation.
  • By default, all manual backups are retained in DDS. You can use a backup to restore a deleted instance.


  1. Log in to the management console.
  2. Click in the upper left corner and select a region and project.
  3. Click Service List. Under Database, click Document Database Service.
  4. On the Instance Management page, locate the target DB instance on the Clusters tab or the Replica Sets tab and choose More > Delete.
  5. In the displayed dialog box, click Yes.
