# simple windows backup system
# I was fed up to continuously reinstall my mum's windows so I came up
# with this system.
# she has 3 partitions as follows:
# hda1- windows system partition (15GB)
# hda2- a swapless basic debian partition (20GB)
# hda3- windows data partition
#
# * windows is configured so the user data are on the windows data partition
#
# * on the debian partition, the script is installed as /root/winbackup.sh
# with rights 0777
#
# * the /etc/inittab file is modified so:
#1:2345:respawn:/sbin/getty 38400 tty1
# now says
#1:2345:respawn:/root/winbackup.sh
#
# * I have created a /data rep 
#
# * the packages ntfs-3g and ntfsprogs are installed
# 
# BUGS: sometimes (when the ntfs partition is unclean), ntfsclone exists
# and I can't seem to capture a non zero result
#
# change the windows system partition path below:
WINDOWS_PART=/dev/hda1
IMAGE=/data/xp.ntfs
