You can probably figure it out from this little script I have on a SunOS
machine. You'll probably also see that I had it it doing local backups
originally:
#!/bin/sh
#
# Example dump for level 0 - modified dir
#
# show when we started...
date
# set vars
DUMP=/usr/etc/dump
HOST=ickis
TAPE=/dev/nrst5
#
# Rewind the tape
#
echo Rewind the tape...
###mt -f $TAPE rewind
rsh -n -l root $HOST mt -f $TAPE rewind
#
# For each partition
