+## Backup and restore
+From the settings page you can backup your metadata into a zip file. The file will get stored at *cache/backup* and will contain the necessary files to restore the Elasticsearch index formated **nd-json** files as well a complete export of the index in a set of conventional **json** files.  
+
+The restore functionality will expect the same zip file in *cache/backup* and will recreate the index from the snapshot.  
+
+BE AWARE: This will **replace** your current index with the one from the backup file.
