Clonezilla DRBL Tutorial for Debian 6.0.1 and Ubuntu 10.10

Clonezilla is a free disaster recovery, disk cloning, disk imaging and deployment solution.[3] Clonezilla is designed by Steven Shiau and developed by the NCHC Free Software Labs in Taiwan. Clonezilla SE provides multicast support similar to Norton Ghost Corporate Edition.

Clonezilla Server Edition (SE)

  • A single command is required to switch the client environment
  • DRBL, FreeDOS, OS in local HD, memtest
  • Linux network installation
  • Not suitable for older machines and/or thin clients //NOTE// From version 5 (released ’07), fat client mechanism is supported in LTSP

Network Setup for Linux Server

Install the GNU/Linux distribution and configure all network cards. In the following, we use “eth0” to connect the Internet, while eth1, eth2, eth3 are for DRBL environment (set the network card’s IP addresses to be private Ips (i.e. 192.168.x.x, the following example, we set eth1:, eth2:, eth3:…); Please remember this principle, private IP (e.g. 192.168.x.x) is used for DRBL environment.

#sudo vim /etc/network/interfaces

Edit the Following Lines.

# The loopback network interface
auto lo
iface lo inet loopback

#Gateway –
auto eth0
iface eth0 inet dhcp
pre-up iptables-restore < /etc/iptables.rules
post-down iptables-save > /etc/iptables.rules

auto eth1
iface eth1 inet static

auto eth2
iface eth2 inet static

auto eth3
iface eth3 inet static

Clone computer

Clonezilla Network

If you do not have multiple Interface make virtual interface. Here it goes.

auto lo
iface lo inet loopback

#Network Interface, this should match your network
# Connect eth0 to internet.
auto eth0
iface eth0 inet dynamic

#Virtual Interface for Conezilla, make sure you use a "class C" IP (192.168.x.x)
auto eth0:0
iface eth0:0 inet static

Restart network

sudo /etc/init.d/networking restart

CloneZilla Server Edition Installation Steps

Initiall you need to import the GPG key of the DRBL (Diskless Remote Boot in Linux, needed to boot the client systems from the network (PXE) later on) and CloneZilla repository to do this you need to follow me.

wget -q http://drbl.sourceforge.net/GPG-KEY-DRBL -O- | apt-key add –

We add some repository list in /etc/apt/sources.list

vim /etc/apt/sources.list

Add the DRBL/CloneZilla Debian repository to it:

deb http://archive.ubuntu.com/ubuntu maverick main restricted universe multiverse # (Or any Ubuntu mirror site near you)

deb http://drbl.sourceforge.net/drbl-core drbl stable


apt-get update


Now we can install DRBL and CloneZilla like this:

apt-get install drbl

Then we run


Configure DRBL and CloneZilla with default values.


This script is for those impatient, it will setup the DRBL server by the default value which might not fit your environment. Are you impatient ?

[Y/n] <– ENTER


Ok, Laziness is a virtue! Let us setup DRBL server with the default values!!!

Press “Enter” to continue… <– ENTER



Enjoy DRBL!!!

If you like, you can reboot the DRBL server now to make sure everything is ready…(This is not necessary, just an option.).


DRBL server is ready! Now set the client machines to boot from PXE or Etherboot (refer to http://drbl.sourceforge.net for more details).

NOTE! If Etherboot is used in client machine, version 5.4.0 or newer is required!

PS. The config file is saved as /etc/drbl/drblpush.conf. Therefore if you want to run drblpush with the same config again, you may run it as: /opt/drbl/sbin/drblpush -c /etc/drbl/drblpush.conf


Installation process Ends here.

Create an Image of a Linux System

To create an image, we first start CloneZilla on the Ubuntu/Debian system and tell it to store an image (the server will then wait until a client connects to store the image), and then we boot the client system of which we want to create the image from the network – it should then boot into a CloneZilla Linux system that connects to the server and creates the image.



on the Ubuntu/Debian server and select All Select all clients:

Next pick clonezilla-start Start_clonezilla_mode:

Choose save-disk Save client disk as an image:

Select Later_in_client Later input image and device name in client (you will then be prompted for an image name later on the client, instead of having to provide an image name now):

On the next two screens you can simply press ENTER to select the default values:

Select the action when the client finishes cloning (I want to shut down the client after the image has been created, so I select -p poweroff):

Press ENTER again on the next two screens to accept the default values:

Note: Leave default value.

Press ENTER again:

The server is now ready. Now start the client system that you want to clone. It is important that you boot it from the network (via PXE) – you might have to adjust the boot order in the client’s BIOS so that it boots via PXE:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/11.png

After you’ve configured the client to boot from the network, you should see a DRBL boot menu. Select Clonezilla: save disk (choose later) as image (choose later):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/13.png

Next provide a name for the image (or accept the default value):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/14.png

Select the source hard drive:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/15.png

Afterwards, the image is being created and transferred to the CloneZilla server:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/16.png

Then the CloneZilla server is notified that the image creation process has finished…

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/17.png

and the client system is shut down (or rebooted – that depends on the action you’ve chosen on the server):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/18.png

That’s it, we now have an image of our Linux system that we can clone to other systems.

4 Cloning/Restoring The Image

To clone or restore the image to other systems, run


Select All Select all clients:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/19.png

Choose clonezilla-start Start_clonezilla_mode:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/20.png

Select restore-disk Restore an image to client disk:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/21.png

You can accept the default values on the next four screens by pressing ENTER:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/22.png

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/23.png

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/24.png

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/25.png

Pick the image that you want to restore:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/26.png

Choose the target hard drive:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/27.png

Select multicast multicast restore:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/28.png

Choose clients+time-to-wait:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/29.png

Fill in the number of systems on which you want to restore the image (I want to restore just one system in this example):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/30.png

Fill in the max. time (in seconds) that the server will wait until all clients are powered on (i.e., if you want to restore the image on ten clients, you have 300 seconds to power on the other nine computers after you have powered on the first one – if you are too slow, CloneZilla will start to restore the image only on the systems that have been powered on in time):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/31.png

Afterwards, press ENTER twice:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/32.png

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/33.png

Your Server side work is over.

Restoring Client

Now power on the clients. Make sure they are configured to boot from the network (via PXE):

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/34.png

In the boot menu, select Clonezilla: multicast restore or donot touch. Just power on your system and see for PXE boot.

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/35.png

The cloning process will then begin:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/36.png

Afterwards, the server will be notified that the process has finished…

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/38.png

and the client system will reboot:

説明: http://static.howtoforge.com/images/clonezilla_se_on_debian_etch/39.png

Before the client system boots, enter its BIOS again and configure it to boot from the hard drive!

If all goes well, the computer should boot into the cloned operating system.
