I personally use afio to back up four HP-UX boxes to one DAT drive. I
don't use cpio often enough to answer your question specifically, but
this is the way I do it with afio:

remsh DAThost dd if=/dev/DAT bs=1024k | afio -i -

The - represents standard input. Using the standard output of a remsh dd is
a good way to go. I do something very similar to back the machines up.

find / -print | afio -o - | remsh DAThost dd of=/dev/DAT bs=1024k

I hope this helps.

If you change the literal "rsh" (somewhere around line 584) to whatever
works on your system, afio will internally generate the remote command
for you when it sees a device name in the form host:device, running
another copy of afio on the other system instead of dd.

If people are going to do selective restores over a network though, it
might be worth modifying the code to do the selection on the machine
with the tape drive instead of streaming the whole DAT across the net
for the local copy to discard most of it.
