Clonezilla
Is used to facilitate system deployment, bare metal backup, and recovery, it is often compared to commercial solutions like Norton Ghost and Acronis True Image. However, what makes Clonezilla different is its feature set, wide platform support, and open-source nature, making it both accessible and adaptable for a range of users from individual home users to large enterprise IT administrators.
It is a partition and disk imaging and cloning program. It allows users to create exact copies (images) of computer drives or partitions and later restore them as needed. This makes Clonezilla highly valuable for tasks such as full system backups, system migrations, disaster recovery, and mass deployment of operating system images across multiple computers. It is as effective in restoring a single machine as it is in copying the configuration of one machine to dozens or even hundreds of others.
