Clonezilla is a partition and disk cloning application for Linux, Free-, Net-, and OpenBSD, Mac OS X, Windows, and Minix. It supports all the major filesystems including EXT, NTFS, FAT, XFS, JFS, and Btrfs, LVM2, and VMWare’s enterprise clustering filesystems VMFS3 and VMFS5. Clonezilla supports 32- and 64-bit systems, both legacy and UEFI BIOS, and both MBR and GPT partition tables. It’s a good tool for backing up a complete Windows system with all of your installed applications, and I like it for making copies of Linux test systems so that I can trash them with mad experiments and then quickly restore them.
