Clonezilla

Block-level copying Clonezilla can operate on block-level (sector by sector). Thus, its operation could be file system-agnostic. In other words, it can clone one disk to another without knowing what partitions or file systems the source disk has. This indiscriminate approach, however, is inefficient because it would mean copying every block, even if it does not contain meaningful data. Therefore, Clonezilla uses a smart file system-aware approach. It uses information from the file system to determine which blocks on a drive require copying. This ensures that only the space currently in use on the drive is copied while empty space is ignored. Clonezilla supports Ext2, Ext3, Ext4, ReiserFS, XFS, JFS, Btrfs, NTFS, FAT, exFAT and more. For unsupported file systems, Clonezilla falls back to indiscriminate block-level copying. Drive images can be split into smaller files and compressed to save space on the destination drive. In addition, it can mount BitLocker-encrypted volumes. PXE booting Clonezilla can be booted over a computer network using PXE booting techniques. == Variants ==

There are two variants of Clonezilla: Clonezilla Live is intended to be used for imaging a single computer, while Clonezilla Server Edition (SE) is intended for mass deployment over a computer network. == Effectiveness and limitations==

Clonezilla is an effective tool for deploying software in training laboratories. == See also ==
