-      This mode (`pg-backupapi`) was introduced in v5.4.0 as a way to further integrate with Barman letting Barman
-      handle the restore. This also reduces the ssh keys that need to share between the backup and postgres nodes.
-      As long as you have access to the API service by HTTP calls, you could perform recoveries right away.
-      You just need to instruct Barman through the API which backup you need and on which node the backup needs to
-      to be restored on.
-    </para>
-
-    <para>
-      In order to enable <literal>pg_backupapi mode</literal> support for <command>repmgr standby clone</command>,
-      you need the following lines in repmgr.conf:
-      <itemizedlist spacing="compact" mark="bullet">
-        <listitem><para>pg_backupapi_host: Where pg-backup-api is hosted</para></listitem>
-        <listitem><para>pg_backupapi_node_name: Name of the server as understood by Barman</para></listitem>

-      </itemizedlist>
-
-      This is an example of how repmgr.conf would look like:
-
-      <programlisting>
-        pg_backupapi_host = '192.168.122.154'
-        pg_backupapi_node_name = 'burrito'

-      </programlisting>

-
-    <para>
-      <literal>pg_backupapi_host</literal> is the variable name that enables this mode, and when you set it,
-      all the rest of the above variables are required. Also, remember that this service is just an interface
-      between Barman and repmgr, hence if something fails during a recovery, you should check Barman's logs upon
-      why the process couldn't finish properly.
-    </para>
-
-    <note>
-      <simpara>
-        Despite in Barman you can define shortcuts like "lastest" or "oldest", they are not supported for the
