# Based on a script by Daniel O'Callaghan <danny@freebsd.org>
#Change the 5 variables below to fit your computer/backup
COMPUTER=hogan # name of this computer
DIRECTORIES="/etc /www /usr/local /var/named /var/log"
# directoris to backup
BACKUPDIR=/deskstar/backups # where to store the backups
TIMEDIR=/deskstar/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.
