In Google Cloud SQL, adding labels directly to backups is not supported. Labels can be associated with Cloud SQL instances, but not individual backups. Despite this limitation, there are workarounds and alternative approaches to manage backup metadata effectively.
One method is indirect labeling through instances. By adding labels to a Cloud SQL instance, you indirectly apply these labels to all backups created from that instance. This approach allows you to filter or identify backups based on the instance's labels when listing or managing them.
Another approach involves embedding custom metadata in backup names. When creating backups manually, you can customize the backup name to include relevant information such as a project identifier, environment, or other custom tags. This method helps organize and filter backups based on the information embedded in their names.
Additionally, you can maintain an external tracking system. This involves creating a separate database table, spreadsheet, or custom metadata store to track backups and their associated labels. When a backup is created, you store its details, such as backup ID and instance name, along with custom labels in your external index.
While direct labeling of Google Cloud SQL backups is not possible, you can effectively manage backup metadata through indirect labeling, custom backup names, and external tracking systems. These workarounds ensure that you can organize and filter your backups efficiently despite the current limitations.
