In the meantime, is it not possible to do your backup over raw TCP/IP? I
don't know whether NFS interferes with TCP/IP (I'd be surprised if it
did, but I've never run NFS).  Over TCP/IP, we use something like the
following (run as root on the machine being backed up):

  # find . -depth -print | cpio -oc | \
    su bin -c "/usr/ucb/rsh tape_machine dd ibs=1024k obs=1024k of=/dev/tape"

I realize this isn't exactly what you want, but isn't it a least a
suitable workaround?  (This, of course, completely ignores what I
think is the real, albeit unstated, point of Karl's postings on this
subject: that ISC doesn't fix bugs fast enough to suit him.  My apologies
if I've insulted you or gotten this wrong in some way, Karl.)
