make an image backup of a pc

1. download resque CD (395mb)
2. burn it on a cd/dvd
3. boot the pc where you want to recover the data
4. mount -t cifs //192.168.1.5/Share /mnt/windows -o username=MyWindowsAccount
5. type in your password
6. ddresque -d -r3 /dev/sda1 /mnt/windows/sda1.img sda1.log
7. open the share on your windows pc
8. and open the image wit 7-zip. You can access now all files of the pc.

other tips :

when having a wireless network, but configuring your wireless everytime you boot can be show-stopper. I bought a wireless extender WLX-2001. you get the benefits of both wireless and wired network. a hight troughput from trouble-pc to server-pc, but you can do it everywhere.

another program to open this image file is VDK from vmware.



Update 23/12/2014 : Opening the Image on a linux machine:

I'm a Windows Guy (until Now!). but i had some trouble to mount the image on a linux pc.

First, create a new mountingpoint in the /mnt/ folder.
sudo mkdir /mnt/olddisk

The next step i did (but i don't think its necessary)
sudo fsck -y /media/User1/TOSHIBA\ EXT/public/file1a.img

and then i mounted my image in a regular way :
sudo mount /media/User1/TOSHIBA\ EXT/public/file1a.img /mnt/olddisk
