+<p>The <code>media_ids</code> folder contains only the metadata of the media uploaded by the user.
+It does not contain the media itself.
+Furthermore, only the <code>media_ids</code> that Synapse manages itself are exported.
+If another media repository (e.g. <a href="https://github.com/turt2live/matrix-media-repo">matrix-media-repo</a>)
+is used, the data must be exported separately.</p>
+<p>With the <code>media_ids</code> the media files can be downloaded.
+Media that have been sent in encrypted rooms are only retrieved in encrypted form.

+#   repository_url: Address of the media repository resp. media worker.
+#   serverName: Name of the server (`server_name` from homeserver.yaml).
