I use tar.  Have had no problems with it.  I have had afio hang on me
tho.  Anyway this is the backup script I use everyday.

Here is what I use:


# Backup 1.5 90/03/03 11:25:56
# tape backup script

PATH=$PATH:/usr/devbin:/etc
export PATH

case $1 in
	-d)
	delay=$2
	;;
	*)
	delay=300
	;;
esac
# notify any users
echo "
		    W A R N I N G !!!

	A backup to tape will be started in five (5) minutes.  You 
	will be logged off at that time if you are still here.  This
	is necesary so no data is lost, the backup goes as fast
	as possible and the integrity of it is maximum.  The system will
	take calls again when it is finished.

	Thank you.
	Administration

done

# backup the files to tape

cd /

# put passwd back to normal, so it will allow logins.
