Clonezilla Disk Cloning Tool

Clonezilla is a free, open-source partition and disk imaging and cloning program similar to Norton Ghost, designed for system deployment, bare metal backup and recovery, and disk cloning. Created by Steven Shiau at the National Center for High-Performance Computing (NCHC) in Taiwan in 2007, Clonezilla has become the most popular open-source disk cloning tool, downloaded millions of times and used by IT departments worldwide. Key features include: disk and partition cloning (creating exact copies of entire disks or individual partitions, including boot sectors, file systems, and partition tables), image creation and restoration (saving disk images to local storage, network shares including NFS, SSH, and Samba, or dedicated Clonezilla Server), three editions (Clonezilla Live for single-machine use via bootable USB or CD, Clonezilla Lite Server for multicast deployment to up to 40 computers, and Clonezilla SE for enterprise-scale unicast and multicast deployment to hundreds of machines), file system support (ext2, ext3, ext4, ReiserFS, Reiser4, XFS, JFS, Btrfs, FAT12, FAT16, FAT32, NTFS, HFS+, UFS, VMFS, and minix), block-level cloning (sector-by-sector copying for unsupported file systems), compression (gzip, zstd, and xz compression of images to reduce storage and bandwidth), multicasting (Clonezilla SE supports multicast deployment, simultaneously imaging hundreds of machines over the network), encryption (LUKS-encrypted image storage for secure backups), UEFI and BIOS support (booting and cloning both UEFI and legacy BIOS systems), GPT and MBR partition tables (full support for both partition table types including hybrid configurations), post-clone scripts (running custom scripts after cloning for hostname changes, network configuration, and domain joining), and integration with DRBL and PXE (deploying via network boot in DRBL and PXE environments).
