A system to manage database management system backup objects may include an external storage component storing a first database management system backup object. A database management system node (e.g., associated with a database as a service cluster of a hyper-scalar infrastructure) may be configured to write information to and read information from the external storage component without being able to delete information in the external storage component. A backup housekeeping component, independent of the database management system node, may trigger a request to retrieve backup requirement information (e.g., associated with a maximum backup age, a latest backup identifier, an indication of a newest backup to be deleted, etc.) from the database management system node. The backup housekeeping component may then delete all database management system backup objects in the external storage component that are no longer required, including the first database management object, based on the retrieved backup requirement information.
