This technology also allows you to “bake in” applications and configurations to simplify deployments. The biggest advantage for imaging is you can create a single reference machine configured exactly to your environment’s needs and capture it for mass deployment. When creating system images for Microsoft Windows computers, it is highly recommended to take advantage of the built-in SysPrep utility which removes all unique hardware and software identifiers that may have been captured from the source computer. To ensure that all employees in given roles start out with the same basic configuration, IT can create disk images for each role/department. That way, when the destination computer boots for the first time, it will stand up as a new device with all files and applications of the source computer.Ī typical use case arises when you on-board new employees and provision them with new devices, such as laptops or desktop computers.
The most common use is to capture an image of one computer and deploy it to other computers. For the purposes of this post, we will be focusing on systems deployment exclusively. Disk images can also span across different operating systems such as Windows, MacOS, and Linux. They can be used for backing up files, creating virtual computers in a hypervisor (VMWare, Hyper-V, etc.), as well as for systems deployment. Many distinct types of disc images exist.
What is disk imaging?ĭisk imaging is the process of copying the contents of a drive and storing it into a single compressed file. In this blog post, I’ll cover what disk imaging is, why it matters, and its advantages, disadvantages, and best practices. The goal of disk imaging is to take a backup of all the data stored on a device at a point in time and preserve it for later use.
