This question was asked in another group and the response seems to be to
use a program on the UNIX side called bru (or BRU? or Bru? or bRu? or ...).
On my 3000UX this 'bru' fellow is invisible! The manual mentions  cpio  and
the man pages mention  backup. 
I mention the above confusion because I am also confused by it and would
appreciate clarification from anyone.
   
Would some kind soul clearly write instructions to accomplish this?

Many thanks,
