Creating disk images with fsdisk

Introduction

Creating disk images is a useful process when you need to backup or copy the contents of a disk or partition. One tool that can help with this task is fsdisk, a command-line utility that allows you to create, modify, and manage disk partitions on Linux systems. In this article, we will explore how to use fsdisk to create disk images.

Installing fsdisk

Before you can start creating disk images with fsdisk, you need to make sure that the utility is installed on your system. fsdisk is typically included in the util-linux package, which is installed by default on most Linux distributions. If fsdisk is not already installed on your system, you can install it using your package manager. For example, on Debian-based systems, you can install fsdisk by running the following command:

Creating a Disk Image

Once fsdisk is installed on your system, you can start creating disk images. The first step is to identify the disk or partition that you want to create an image of. You can use the fdisk -l command to list all disks and partitions on your system. Once you have identified the disk or partition, you can use the dd command to create a disk image. For example, to create an image of the /dev/sda disk, you can run the following command:

Mounting a Disk Image

Once you have created a disk image with fsdisk, you may want to mount it to access its contents. To mount a disk image, you can use the mount command. First, you need to create a mount point, which is a directory where the contents of the disk image will be accessible. You can create a mount point using the mkdir command. For example, to create a mount point named /mnt/image, you can run the following command:
