  <para>The secondary storage NFS export is mounted by the secondary storage VM. Secondary storage
    traffic goes over the management traffic network, even if there is a separate storage network.
    Primary storage traffic goes over the storage network, if available. If you choose to place
    secondary storage NFS servers on the storage network, you must make sure there is a route from
    the management traffic network to the storage network.</para>
