| ```release-note:bug | |
| alloydb: changed `location` from `optional` to `required` for `google_alloydb_backup`. `location` had previously been marked as optional, but operations failed if it was omitted, and there was no way for `location` to be inherited from the provider configuration or from an environment variable. This means there was no way to have a working configuration without `location` specified. | |
