Clonezilla (Clonezilla Live) is an open-source disk imaging and cloning solution designed for system backup, recovery, and large-scale deployment. It creates exact copies of entire disks or individual partitions, making it a practical tool for migration, disaster recovery, and system duplication.
It runs outside the installed operating system, usually from a live USB environment. This ensures that no files are locked during cloning operations and improves consistency and reliability.
