A backup operation has a name of the form ``projects/<project>/instances/<instance>/backups/<backup>/operations/<operation>``. The long-running operation [metadata][google.longrunning.Operation.metadata] field type ``metadata.type_url`` describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations. Operations returned are ordered by ``operation.metadata.value.progress.start_time`` in descending order starting from the most recently started operation. Args: request (Union[google.cloud.spanner_admin_database_v1.types.ListBackupOperationsRequest, dict]): The request object. The request for [ListBackupOperations][google.spanner.admin.database.v1.DatabaseAdmin.ListBackupOperations]. parent (:class:`str`): Required. The instance of the backup operations. Values are of the form ``projects/<project>/instances/<instance>``. This corresponds to the ``parent`` field on the ``request`` instance; if ``request`` is provided, this should not be set. retry (google.api_core.retry.Retry): Designation of what errors, if any, should be retried. timeout (float): The timeout for this request. metadata (Sequence[Tuple[str, str]]): Strings which should be sent along with the request as metadata. Returns: google.cloud.spanner_admin_database_v1.services.database_admin.pagers.ListBackupOperationsAsyncPager: The response for [ListBackupOperations][google.spanner.admin.database.v1.DatabaseAdmin.ListBackupOperations]. Iterating over this object will yield results and resolve additional pages automatically.
