+# Filesystems
+
+As an ephemeral container, a *phd5* application usually does not store files directly.
+It requires one or more storage backends, which are used for permanent file storage.
+
+Example for storing database dumps on S3. 
+
+    yii db/export && \
+    yii fs/sync runtime://mysql s3:// --interactive=0 && \
+    yii fs/rmdir runtime://mysql --recursive --interactive=0
