GNU tar has -g option to create incremental backups. To make full backup on every sunday, enter:

tar -zcvf /backup/full.tar.gz /home

To make incremental backup enter:
Code:
NOW=$(date +"%d-%m-%Y")
  i=$(date +"%Hh%Mm%Ss")
  FILE="i.$NOW-$i.tar.gz"
  tar -g /root/gnutar.incremental.txt -zcvf /backup/$FILE /home
Read man page for more info:
Code:
man tar
