1) I do not know the details of GNU tar, esp. the meaning of the
"--rsh-command" parameter. I can only guess it would be used
if you gave a "host:device" value for a "-f" parameter,
but you do not do that (might be worth a try).
2) Which shell are you using, and does it support arbitrary size
pipes ? Remember you do it on NT, and IMHO this is not a stable
"base" for many things - pipes being one of them.
(I had to write a program starting two subprograms to communicate
via pipes - a real horror, compared to Unix !)
3) How large is the "tar" file really written to tape ?
I suspect that the pipe mechanism does not work in your setting
for your amount of data.
