In that case, anywhere NDMP tape couldn't be read by non-NDMP drive, =
the
cloning will fail. If clone from one filer NDMP drive to media server
non-NDMP drive, that meant we read in NDMP format then written in =
non-NDMP
format(let say possible), in the case of recovery, how can we recover
non-NDMP format back to original filer ? There are totally in different
format.

It is possible but there are caveats. You can easily duplicate NDMP =
images
on a media server; using the media servers resources.
You can also use the NDMP client's drives, but there is a severe =
performance
penalty in doing this; about a 40% penalty give or take a few =
percentage
points.
The best option I've found is just let the media server do all the
duplications, it's cleaner and faster than any other option.
If by cloning you mean inline copy, then the answer is no. NDMP will =
only
do one stream at a time under NBU.
As to the original posters question, I believe the answer is no. You =
can't
duplicate from one filer to another under 3.4. I don't think you can =
do
that even with 4.5, but you can do it from the filer to the media =
server
(which I bet is why the tape loads in the media server drives). There =
is a
config entry that will disallow NDMP tape loads in non-NDMP drives. I
forget which conf file and the exact syntax, but I know there is at =
least
one person on this list that has the entry....
