Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery. Three types of Clonezilla are available, Clonezilla live, Clonezilla lite server, and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla lite server or SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the hard disk. This increases the clone efficiency. With some high-end hardware in a 42-node cluster, a multicast restoring at rate 8 GB/min was reported.
Features: Many File systems are supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs, f2fs and nilfs2 of GNU/Linux, (2) FAT12, FAT16, FAT32, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, (5) minix of Minix, and (6) VMFS3 and VMFS5 of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, FreeBSD, NetBSD, OpenBSD, Minix, VMWare ESX and Chrome OS/Chromium OS, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored by Partclone. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
LVM2 (LVM version 1 is not) under GNU/Linux is supported.
Boot loader, including grub (version 1 and version 2) and syslinux, could be reinstalled.
Both MBR and GPT partition formats of hard drive are supported. Clonezilla live also can be booted on a BIOS or uEFI machine.
Unattended mode is supported. Almost all steps can be done via commands and options. You can also use a lot of boot parameters to customize your own imaging and cloning.
One image restoring to multiple local devices is supported.
Image could be encrypted. This is done with ecryptfs, a POSIX-compliant enterprise cryptographic stacked filesystem.
Multicast is supported in Clonezilla SE, which is suitable for massive clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
Bittorrent (BT) is supported in Clonezilla lite server, which is suitable for massive deployment. The job for BT mode is done by Ezio.
The image file can be on local disk, ssh server, samba server, NFS server or WebDAV server.
AES-256 encryption could be used to secures data access, storage and transfer.
Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition. However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.
