problem mit backup shell-script

hallo! ich habe ein script für meine backups im netz gefunden, jedoch kommt immer die fehlermeldung:

/bin/tar:  invalid option -- ?

ich habe mir das script schon mal selbst angeschaut, aber ich kann den fehler einfach nicht finden!

liegt es vielleicht an dieser variable?

NEWER=""                                # For incremental backups

hier das skript:

#!/bin/sh 
# full and incremental backup script 
# created 07 February 2000 
# Based on a script by Daniel O?Callaghan <d?@freebsd.org> 
# and modified by Gerhard Mourani <gmour?@videotron.ca> 
# and by Kevin Pfeiffer <kevin-pfeif?@gmx.de> - 16 March 2003 

# Filename:                     backup.cron 
# Script should live in /etc/cron.daily (for example) 

#Change the 6 variables below to fit your computer/backup

DIRECTORIES="/home/amarhe/download /home/amarhe/Documents"
# directories to backup (separate with spaces)

TIMEDIR=$BACKUPDIR/last-full
# where to store date of last full backup

Hallo

Wenn du schon mit -N, --newer=DATUM arbeitest, dann muss vor die Variable mit dem gültigen Datum auch die Option -N oder --newer=$NEWER.
Wenn du das ohnehin nicht willst, dann lass es einfach weg.

An welcher Stelle bricht das Script denn ab?

Sorry, hab es nur überflogen.

IMHO ist es auch ratsam die Variablen zu quoten.
Bsp. TIMEDIR="$BACKUPDIR/last-full"
Ein set -x hilft dir beim Debuggen, da es dir die Inhalte der Variablen ausgibt.

Gruß Wolfgang
