Hello everyone...

Again it seems that I've gotten more responses this time than with my
original post...

Anyway, the two best ways to vdump to a remote machine are:

1) Use: /sbin/vdump -LEVEL -u -b 60 -f - FILESYSTEM | rsh DUMPHOST
/usr/bin/dd of=/dev/tape bs=BLOCKSIZE

or

2) put this into a nifty script called 'rvdump:'

--- Script begins here ---

#!/bin/ksh
#
# rvdump
#
# vdump script which accepts `-f [[user_at_]host:]device' for dumping
# to a remote device
#
# R.P.Bellis 1995
#

# set location of programs used
dd=/bin/dd
getopt=/bin/getopt
rsh=/bin/rsh
tr=/bin/tr
vdump=/sbin/vdump

# parse command line arguments
set -- `$getopt 0123456789CDNVhquvwF:T:b:f:x: $*`
if [ $? != 0 ]
then
        exec $vdump
fi

# set initial variables
level=""
file=""
args=""
bs="60"

# scan argument list
while [ $1 != -- ]
do
        case $1 in
                -[0-9])
                        if [ "$level" = "" ]; then
                          level=$1
                        else
                          exec $vdump
                        fi
                        ;;
                -F|-T|-x)
                        args="$args $1 $2"
                        shift
                        ;;
                -b)
                        bs="$2"
                        shift
                        ;;
                -f)
                        file="$2"
                        shift
                        ;;
                *)
                        args="$args $1"
                        ;;
        esac
        shift
done

# remove -- from arg list
shift

# check for single final parameter
if [ $# -ne 1 ]; then
  exec $vdump
fi

# check for host:device dump file
echo $file | $tr ':' ' ' | read host device

if [ "$device" = "" ]; then # do local device backup

  # run the dump command
  $vdump $level $args -b $bs -f $file $1

else # do remote device backup

  # check for user_at_host
  echo $host | $tr '_at_' ' ' | read user host
  if [ "$host" = "" ]; then
    host=$user
    user=""
  fi

  # add -l flag for `rsh' if a username was specified
  if [ "$user" != "" ]; then
    user="-l $user"
  fi

  # run the dump command
  $vdump $level $args -b $bs -f - $1 | $rsh $host $user $dd of=$device bs=${bs}k

fi

--- end script 'rvdump' ---
