Raspberry Pi SD-card image-back-up to WIn7

1.  Make your last manual image via Win32DiskImager (if something will going wrong)
2.  Watch that video until 1:28 and do it: http://www.youtube.com/watch?v=1_qp74VU5ao
3.  Create a new folder on your Raspi:  /home/pi/mynetworkdrive
4.  Edit the this file:             sudo nano /etc/fstab
5.  Add the following line:     //192.168.x.xxx/folder /home/pi/mynetworkdrive cifs guest,_netdev 0 0
                    replace 192.168.x.xxx with the actual IP-address of your network drive)
6.  Mount the new drive:            sudo mount /home/pi/mynetworkdrive
7.  (Reboot your Raspberry PI:      sudo reboot (just to make sure… maybe not necessary))
8.  Place the following script (raspy_back-up.sh) into:  home/pi/domoticz/scripts
9.  Make it executable and…
10. …exchange the IPadress with your IPadress
    a.  check also if all directories are the same as in the script
    b.  check if you need to have pv installed
    c.  check if you want to stop and start services
11. Save the edited script and start it from PUTTY…
