+Install and configure the backup service
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Optionally, install and configure the backup service. For simplicity,
+this configuration uses the Block Storage node and the Object Storage
+(swift) driver, thus depending on the
+`Object Storage service <https://docs.openstack.org/project-install-guide/object-storage/ocata/>`_.
+
+.. note::
+
+   You must :ref:`install and configure a storage node <cinder-storage>` prior
+   to installing and configuring the backup service.
+
+Install and configure components
+--------------------------------
+
+.. note::
+
+   Perform these steps on the Block Storage node.
+
+#. Install the packages:
+
+   .. code-block:: console
+
+     # apt install cinder-backup
+
+2. Edit the ``/etc/cinder/cinder.conf`` file
+   and complete the following actions:
+
+   * In the ``[DEFAULT]`` section, configure backup options:
+
+     .. path /etc/cinder/cinder.conf
+     .. code-block:: ini
+
+        [DEFAULT]
+        # ...
+        backup_driver = cinder.backup.drivers.swift
+        backup_swift_url = SWIFT_URL
+
+     Replace ``SWIFT_URL`` with the URL of the Object Storage service. The
+     URL can be found by showing the object-store API endpoints:
+
+     .. code-block:: console
+
+      $ openstack catalog show object-store
+
+Finalize installation
+---------------------
+
+Restart the Block Storage backup service:
+
+.. code-block:: console
+
+   # service cinder-backup restart
