here's a simple shell script i wrote before i found the afbackup program.

note: i've updated it slightly to use the 'tempfile' command.  i believe
that this command is only available in hamm.  modify as required if you're
not using hamm


play with this, it will do what you want....however, i strongly
recommend that you investigate the afbackup package. it can do full and
incremental backups - it's a complete backup system, whereas this script
is just a quick-and-dirty hack to get the job done.

TAPE=/dev/st0
LIST=$(tempfile)

if [ "$1" = "--erase" ] ; then 
	mt -f $TAPE erase
fi

# list of directories to exclude from the backup
EXPATHS="/proc /dev /cdrom /dos /mnt \
		 /tmp /usr/tmp /var/tmp \
		 /var/spool/news /var/spool/squid \
		 /usr/src/linux"

# Convert into the form of a regex that find can use.
EXCLUDE=$( echo $EXPATHS | \
	sed -e 's,^,\\\(^,' -e 's, ,$\\\)\\\|\\\(^,g' -e 's,$,$\\\),' )

# now construct the list of files to backup...
find / -regex "$EXCLUDE" -prune -o -print | sort > $LIST

# and finally, do the backup!
cat $LIST | afio -o -c 512 -s 149m -v -z -L /tmp/afio.log -Z -G 9 $TAPE

# now clean up
rm -f $LIST
mt -f $TAPE offline
