+# Backups
+
+There are two important places where your data are located,
+in your database and in your media folder. The following `umap` commands
+might help you to backup these data:
+
+## `backup`
+
+The `backup` command requires a `path` as a parameter where two archives
+will be generated:
+
+* `<path>/database.<isodate>.tar.gz` contains a JSON dump of the database
+  ready to be passed to a `loaddata` command.
+* `<path>/media.<isodate>.tar.gz` contains the content of your media
+  folder as declared in your `MEDIA_ROOT` setting.
+
+### Examples
+
+```
+umap backup /tmp/test_backup
+```
+
+will generate (if run on May, 4th 2017!):
+
+```
+/tmp/test_backup/database.2017-05-04.tar.gz
+/tmp/test_backup/media.2017-05-04.tar.gz
+```
+
+## `sync_backup`
+
+The `sync_backup` command requires a `path` as a parameter and
+a `destination` to synchronize to.
+
+It will take both database and media archives files for the current day
+and `rsync` these to the destination.
+
+### Examples
+
+```
+umap sync_backup /tmp/test_backup root@ip:/backups
+```
+
+will sync generated files from the `backup` command to your distant server.
