Initial Code
# full and incremental backup script
# created 07 February 2000
# Based on a script by Daniel O'Callaghan <[email protected]>
# and modified by Gerhard Mourani <[email protected]>

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

COMPUTER=deep                           	# name of this computer
DIRECTORIES="/home"                     	# 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

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

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

        # Update full backup date
        echo $NOW > $TIMEDIR/$COMPUTER-full-date

# Make incremental backup - overwrite last weeks

        # Get date of last full backup
        NEWER="--newer `cat $TIMEDIR/$COMPUTER-full-date`"
