Onderwerp: Tar Backup script

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.

Code:

#!/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:

Code:

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 ...

dit stuk geeft leeg terug

Code:

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

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

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

Ik hou jullie op de hoogte

Thx
