Maybe I'm on the wrong track because the thought that came to mind was
tee(1), but I'll share anyway.
My thought was
cat datafile | gzip -zc | tee holdingdiskfile | dd if=- of=/dev/tape
or something along those lines. In short, tee takes stdin, sends a
copy to stdout, and also writes it to the file specified on the
command line.
