What is the main use of a system image disk created from your computer?

A system image disk is primarily used for backup and recovery purposes. It creates a complete snapshot of your computer's operating system, applications, and files, allowing you to restore your system to a previous state in case of hardware failure, software corruption, or data loss. This ensures that you can quickly recover your system without needing to reinstall everything from scratch. Additionally, it can be useful for migrating to a new hard drive or computer.
