+About backup to another region for Aiven services
+=================================================
+
+.. important::
+
+    Backup to another region (BTAR) is available on ``:doc:Pro Platform </docs/platform/concepts/pro-platform>``.
+
+Discover the backup to another region (BTAR) feature, check why use it, and learn how it works.
+
+About BTAR
+----------
+
+The backup to another region (BTAR) feature allows existing backup files to be copied from the service's primary backup region to an additional (secondary) region. As a disaster recovery feature, BTAR is particularly useful when the service-hosting region is down since it allows forking the service from an additional copy of the backup residing outside the service-hosting region.
+
+BTAR is currently supported for the following services:
+
+* Aiven for PostgreSQL®
+* Aiven for MySQL®
+
+Why use BTAR
+------------
+
+BTAR provides an additional level of data resilience, helping you make your data safe and protected. BTAR is a cost-efficient low-complexity disaster recovery feature that allows you to replicate your data in a secondary backup region and recover it there in case of outage, downtime, data loss, or data corruption in the primary backup region.
+
+How BTAR works
+--------------
+
+By enabling the backup to another region (BTAR) feature, you create a service backup that is additional to the default backup. This secondary backup is always located in a region of your choice different from the primary backup region.
+
+Secondary backups are generated from primary backups, not from the service itself. For this reason, your secondary backup becomes available only after the primary backup is taken. There might be a data replication lag between the primary region and the secondary region.
+
+Restoring from a secondary backup, for example in case of an outage of the primary region, can be done by creating a fork of the service in the region where the secondary backup is located.

+        Secondary_backups -- Secondary backups \n to restore service X --> Forked_service_X
+        Service_X -- Forking service X \n if primary region down --> Forked_service_X
+
+Limitations
+-----------
+
+* When selecting a cloud region for your additional backup, you need to use the same cloud provider that your service uses.
+* When you want to :ref:`restore your service from an additional backup <fork-and-restore>` and you use a point in time to specify the scope of data to be restored, you need to set up the time to no later than the time of the latest backup.
+* Secondary backup can only be restored in the region where it was stored.
+* Secondary backup is generated only after a primary backup is complete, and there might be a data replication lag between the primary region and the secondary region.

+
+Delete :doc:`an additional service backup </docs/platform/concepts/backup-to-another-region>` from a region other than where primary service backups are stored.
+
+Disable BTAR via console
+------------------------
+
+1. Log in to the `Aiven Console <https://console.aiven.io/>`_.
+2. From the **Services** view, select an Aiven service on which you'd like to disable BTAR.
+3. On your service's page, select **Backups** from the sidebar.
+4. On the **Backups** page, select the actions (**...**) menu > **Secondary backup location**.
+5. In the **Edit secondary backup location** window, select **Disable**.
+
+Your additional service backup is no longer visible on your service's **Backups** page in the **Secondary backup location** column.
+
+Disable BTAR via CLI
+--------------------
+
+To remove secondary backups for your service, use the :ref:`avn service update <avn-cli-service-update>` command to remove all target regions names from the ``additional_backup_regions`` array.
+
+.. code-block:: bash
+
+    avn service update your-sevice-name                   \

+Disable BTAR via API
+--------------------
+
+To remove secondary backups for your service, use the `ServiceUpdate <https://api.aiven.io/doc/#tag/Service/operation/ServiceUpdate>`_ endpoint to remove all target regions names from the ``additional_backup_regions`` array.

+Add a backup to another region
+==============================
+
+.. important::
+
+    Backup to another region (BTAR) is available on ``:doc:Pro Platform </docs/platform/concepts/pro-platform>``.
+
+Enable :doc:`the backup to another region (BTAR) feature </docs/platform/concepts/backup-to-another-region>` and create an additional cross-region service backup on top of a regular backup stored in the region where your service is hosted.
+
+About enabling BTAR
+-------------------
+
+Tools
+'''''
+
+To add an additional service backup for your service, you can use the following tools:
+
+* `Aiven console <https://console.aiven.io/>`_
+* CLI
+* API
+
+Limitations
+'''''''''''
+
+* Currently, BTAR is supported for Aiven for MySQL® and Aiven for PostgreSQL® only.
+
+Prerequisites
+-------------
+
+* Aiven organization, project, and service
+* ``:doc:Pro Platform </docs/platform/concepts/pro-platform>`` enabled
