The request lacks valid authentication credentials.
The requested physicalTenantId does not exist in this cluster.
The backup could not be deleted from every targeted physical tenant, so it may still exist on some of them. The deletions that already succeeded are not undone, so a retry has only the remaining tenants left to reach.
The service is currently unavailable. This may happen only on some requests where the system creates backpressure to prevent the server's compute resources from being exhausted, avoiding more severe failures. In this case, the title of the error object contains RESOURCE_EXHAUSTED. Clients are recommended to eventually retry those requests after a backoff period. You can learn more about the backpressure mechanism here: https://docs.camunda.io/docs/components/zeebe/technical-concepts/internal-processing/#handling-backpressure .
