How to use Clonezilla to Backup your Computer

The following walkthrough will show you how to backup and create a disk image of your local disk.

Step 1. Download the latest ISO file.

You can download the latest ISO from this official link.

Step 2. Prepare your backup drive

Since we are going to create a disk image, you will need to have a drive (we recommend external drive) that has free space large enough to hold the backup. If you are planning to save the backup image in the network drive such as NAS or Samba Server, make sure you have sufficient space. The insufficient space on the backup destination will lead to unsuccessful backup process.

Step 2. Boot your computer with the ISO

We recommend you to create Clonezilla Live USB to boot your computer from. You can use free tool such as Rufus or Ethcer to create Live USB from Windows machine. Don’t forget to set your boot sequence from BIOS.

On the first screen

Select language. Clonezilla support many languages. Select your language from the list and press Enter.

Select keymap. If you don’t know which one to select, leave it as is. Or select Don’t touch keymap.

Select Start Clonezilla

Select the cloning/backup mode. There are several modes you can choose from. For example, you can select Device-Image to create image from your hard disk. Or you can also use device-Device when you want to clone your existing disk to another. In this case, both disk must be online.

On this example, I choose Device-Image mode. Next, we can select where to save the image. There are several storage we can use to store the image file. You can store your image backup file on local disk, external disk, Samba server, ssh server, s3 server, webdav server and nfs server.

Local Disk

If you want to save your image file to local disk, make sure you have another disks connected to your computer. This is the easiest way to save the image file.


Clonezilla support WebDAV. In this example, I am going to show you how to save Clonezilla backup Image on cloud storage. I was amazed to know that we can save the backup image directly to If you want to save the backup image to, on the following screen wizard, select WebDAV

Amazon S3 Server

Select S3_server if you are planning to save the image to your Amazon S3 storage. It is a great feature on Clonezilla to save the backup image in the cloud storage such as Amazon S3.

SSH Server

You can save the backup image to remote server via SSH. To do so, select ssh_server from the list and then enter the remote SSH server credentials.

Samba Server

Samba server is another great place to store our image. If your network has a samba server running, you can save the image to the samba shared folder.

On this example, we use ssh server to store our image backup. You are free to use another storage. Next, we need to enter the IP address of the remote server where we want to save the backup. We are going to mount the remote file system.

Enter the ssh port. The default is 22

Next, enter the user name for the remote server. Please note that the user must have write permission to the next mount folder.

Now specify the directory of the remote server where we want to save our backup image. For example, we want to put the backup inside /mnt/ directory

Next you will need to enter the password

Once you are connected to the remote server, we can continue to the next step as follow. Select beginner if you are new to Clonezilla. We do recommend this mode for easiest way.
