    the destination is the same as if you were using ssh only ...
    znapzend still uses ssh to discover the snapshots present at the
    remote end, and to launch the mbuffer command at the receiving end
    ....

        znapzendzetup create --recursive --mbuffer=/opt/omni/bin/mbuffer:13872 \
           --mbuffersize=1G --tsformat='%Y-%m-%d-%H%M%S' \
           SRC '7d=>1h,30d=>4h,90d=>1d' tank/home \
           DST:a '7d=>1h,30d=>4h,90d=>1d,1y=>1w,10y=>1month' root at bserv:backup/home

    cheers
