I just tested it on my system. If you want to start the process on any other day you can just change 01, I guess Sun is an ok weekly full backup date.
make sure you put quotes around all the variables. change -cf to -Pcf, this makes the paths absolute (leading slash not removed). I'm here if you need me.

Pretty much the same features. Simple is my middle name. I think I'll use this script. Now is the following okay? Will it work as is? Step 1. wait for Oct 31st, since this cron script will run the next morning 2. on Oct 31st, login as root 3. create the file backup.sh, as below, in /etc/cron.daily/ 4. set perms of backup.sh to 755 5. md /backups/last-full 6. logout and let cron do its thing #!/bin/sh # 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=liholiho-ltsp1 # 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 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.
