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.
