Tar Backup script

[GlobalServe]

Hoi,

Zit met een volgend probleem.
Ik draai een script, maar krijg altijd een rare fout, heb er mij al suf op gezocht, maar vind het probleem niet.

#!/bin/sh
# full and incremental backup script
# created 07 February 2000
# Based on a script by Daniel O'Callaghan <danny@freebsd.org>
# and modified by Gerhard Mourani <gmourani@videotron.ca>

#Change the 5 variables below to fit your computer/backup

COMPUTER=IP72                                   # name of this computer
DIRECTORIES="/var"                              # directoris to backup
BACKUPDIR=/backups                              # where to store the backups
TIMEDIR=/backups/last-full                      # where to store time of full backup
TAR=/bin/tar                                    # name and locaction of tar

#You should not have to change anything below here

PATH=/usr/local/bin:/usr/bin:/bin
DOW=`date +%a`                          # Day of the week e.g. Mon
DOM=`date +%d`                          # Date of the Month e.g. 27
DM=`date +%d%b`                         # Date and Month e.g. 27Sep

# On the 1st of the month a permanet full backup is made
# Every Sunday a full backup is made - overwriting last Sundays backup
# The rest of the time an incremental backup is made. Each incremental
# backup overwrites last weeks incremental backup of the same name.
#
# if NEWER = "", then tar backs up all files in the directories
# otherwise it backs up files newer than the NEWER date. NEWER
# gets it date from the file written every Sunday.


# Monthly full backup
if [ $DOM = "01" ]; then
        NEWER=""
                $TAR $NEWER -cf $BACKUPDIR/$COMPUTER-$DM.tar $DIRECTORIES
                fi

                # Weekly full backup
                if [ $DOW = "Sun" ]; then
                        NEWER=""
                                NOW=`date +%d-%b`

                                        # Update full backup date
                                                echo $NOW > $TIMEDIR/$COMPUTER-full-date
                                                        $TAR $NEWER -cf $BACKUPDIR/$COMPUTER-$DOW.tar $DIRECTORIES

                                                        # Make incremental backup - overwrite last weeks
                                                        else

                                                                # Get date of last full backup
                                                                        NEWER="--newer `cat $TIMEDIR/$COMPUTER-full-date`"
                                                                                $TAR $NEWER -cf $BACKUPDIR/$COMPUTER-$DOW.tar $DIRECTORIES
                                                                                fi

Error output:

lws4:/backups# /etc/cron.daily/backup.cron 
/bin/tar: Substituting -9223372036854775807 for unknown date format `-cf'
/bin/tar: You must specify one of the `-Acdtrux' options

Alvast bedankt voor het eens te bekijken.

Foutje heeft te maken met de "-cf" in deze regel :

$TAR $NEWER -cf $BACKUPDIR/$COMPUTER-$DOW.tar $DIRECTORIES

In die richting moet je zoeken ...

[t.bloo]

dit stuk geeft leeg terug

`cat $TIMEDIR/$COMPUTER-full-date`

en dat komt omdat pas op zondag er iets in die file geschreven wordt

[GlobalServe]

OK, lijkt te werken nu
Heb even aangepast in script. Nu doet die wel de backup.

Ik hou jullie op de hoogte

Thx
