Clonezilla is a free, open-source disk imaging and cloning program that creates backups and deploys disk images across multiple computers. Used by system administrators and power users worldwide, Clonezilla provides enterprise-grade capabilities for protecting systems and rapid deployment.
The software supports most file systems including ext4, NTFS, FAT32, HFS+, APFS, and many more. Only used blocks are copied, making images smaller than full disk size. Compression further reduces storage requirements for backups.
Clonezilla Live boots from USB or CD without requiring installation. The ncurses interface guides users through backup and restore operations. Beginner mode simplifies choices while expert mode provides complete control over advanced options.
Disk-to-disk cloning duplicates one drive to another directly, perfect for drive upgrades. Disk-to-image backup creates archive files that restore systems to any identical or larger disk. Image repositories can reside on local drives, USB devices, or network locations.
Clonezilla Server Edition (SE) deploys images to multiple computers simultaneously using multicast. One transmission serves many receivers efficiently for computer lab setup. Unattended mode automates deployment for large-scale rollouts.
Encryption options protect disk images containing sensitive data. Differential backup stores only changes since the last full backup. Restoration handles smaller target disks when filesystem content fits. BitTorrent-based deployment reduces network infrastructure requirements for massive deployments.
