        for each location.</para>

        <para>Platform Snapshots allow users to store, manage and restore
            snapshots of the Enea Edge Runtime configuration, with the purpose

            disabled by default.</para>

            <para>VNF Snapshots allow users to store, manage and restore
            snapshots of VNFs deployed on the Enea Edge Runtime, with the

            feature is disabled by default.</para>

        <note>
          <para>Users that would like to try out the Snapshot features should
