1. How to setup a Clonezilla server ?

A DRBL server must first be set up in order to use Clonezilla to do massively clone. You can use DRBL Live without installation it on a server, or to install and configure DRBL on GNU/Linux system. To install and configure a DRBL server, check this installation doc then follow it to setup such a Clonezilla server. The setup might take about 30 minutes to a few hours, it depends on your internet bandwidth. Once DRBL is installed on the server, Clonezilla is ready.

Besides, a testing feature to use Clonezilla live as the OS of client in Clonezilla SE can be found here.

When setting up the DRBL server, it is recommended to collect the MAC addresses of the client computers and let the DRBL server offer the same IP address for the clients every time it boots. If you prefer to use DRBL live, remember to isolate the network environment from others. This will keep you from cloning the system to incorrect or unknown clients. Besides, if you do not provide the static IP address to client, different operating systems (like GNU/Linux and MS windows), they use different DHCP client ID. Therefore even it's the same client, when it boots GNU/Linux via DRBL, it will leases one IP address, then next time when it boots into local MS windows, it will lease another different IP address. This is annoying sometimes. However, if you are 100% certain that no other computer will be involved in the DRBL environment, and you do not care about the different IP address leasing problem, you can use the range in dhcpd.conf. In this case, you can even use the "impatient method" to setup the DRBL environment.

2. How to use Clonezilla server edition ?

As root, run "/opt/drbl/sbin/dcs" in DRBL server to switch clients' mode. You will see two menus: clonezilla-start and clonezilla-stop like this:

Check clonezilla-start by "space" key, various modes will be shown:

clonezilla-save-disk: clonezilla save disk mode
clonezilla-restore-disk: clonezilla restore disk mode
clonezilla-save-parts: clonezilla save partitions mode
clonezilla-restore-parts: clonezilla restore partitions mode
This is what the graphic mode looks like:

Examples:

The following is an example of how to save an image from a single computer (called computer M) and then restore it to 39 computers in a 40-computer classroom:
- Set the Clonezilla server to be clonezilla-save-disk mode: In the Clonezilla server,
  - run "/opt/drbl/sbin/dcs", then choose "clonezilla-start" (use the space key to mark it). Next, choose"clonezilla-save-disk" (use space key to mark it)
- Turn on computer M, set it as network boot (PXE or etherboot) in the BIOS or by pressing the hotkey (refer to your motherboard manual) when it is booting.
- When computer M finishes the network boot, if you do not enter image and device name when running /opt/drbl/sbin/dcs -> clonezilla-start -> clonezilla-save-disk, a prompt will ask you to name the image and choose the device. Now enter the name (e.g. nomorems) and then choose the disk you want to save it to. Otherwise, it will use the image and device name you already inputted in the clonezilla server to save the image.
- Once the image is saved, set the mode to be clonezilla-restore-disk in the Clonezilla server. As an example, in the Clonezilla server,
  - run "/opt/drbl/sbin/dcs". Next, choose "clonezilla-start" (use space key to mark it). Next, choose "clonezilla-restore-disk" (use space key to mark it).
  - The program will ask you which source image to restore. In this example, we chose the image "nomorems."

Make sure the clients (i.e. the computers to be cloned) will boot from the network (PXE or etherboot) then turn on the clients to let them boot from network.
The clients will begin to clone the system image "nomorems" to their harddisks.
Once all clients finish cloning, you can stop clonezilla by /opt/drbl/sbin/dcs -> clonezilla-stop.

More examples are available here.
PS: You can refer to DRBl-winroll to make the restored (cloned) MS Windows with a different hostname automatically.
