+As you can see in this example, both `staticfiles` and `default` use the storage class provided
+by `django-storages` (`storages.backends.s3.S3Storage`), but the `data` one uses a specific class
+(`umap.storage.s3.S3DataStorage`).
+
 In order to store old versions of a layer, the versioning should be activated in the bucket.
