NB – Whilst disk cloning software will work fine when migrating from an old hard drive to a new drive or SSD on an existing system, more involved work might be required when migrating an existing system on to new or simply different hardware! In such cases, the use of disk cloning technology with support for restoring to dissimilar hardware might be required (and will be discussed further down on this page)! This means that the existing system will continue to work exactly as it did before whilst using the old hard disk (but with more disk space available or a faster SSD drive now in-use to improve system performance). For example, when adding a new larger or faster hard disk or SSD drive to an existing PC, the existing drive’s contents can be copied over to this new disk and kept exactly as they were beforehand. Such disk cloning software is especially useful when adding new or upgraded hard disks or SSD drives to an existing PC. Making an exact copy of a disk means that all existing data on the original (source) hard drive including the operating system, any installed applications, system settings plus all existing user data is also copied across to the new hard disk during the process. 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.Disk Cloning software is specialist software which can be used to create an exact (1:1) copy of a computer’s hard drive which is then replicated to a secondary (often bigger or faster) hard drive.However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk. Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition.AES-256 encryption could be used to secures data access, storage and transfer.The image file can be on local disk, ssh server, samba server, NFS server or WebDAV server.Bittorrent (BT) is supported in Clonezilla lite server, which is suitable for massive deployment. 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. Multicast is supported in Clonezilla SE, which is suitable for massive clone.This is done with ecryptfs, a POSIX-compliant enterprise cryptographic stacked filesystem. One image restoring to multiple local devices is supported.You can also use a lot of boot parameters to customize your own imaging and cloning. Almost all steps can be done via commands and options. Clonezilla live also can be booted on a BIOS or uEFI machine. Both MBR and GPT partition formats of hard drive are supported.Boot loader, including grub (version 1 and version 2) and syslinux, could be reinstalled.LUKS (Linux Unified Key Setup) is supported.LVM2 (LVM version 1 is not) under GNU/Linux is supported.For unsupported file system, sector-to-sector copy is done by dd in Clonezilla. For these file systems, only used blocks in partition are saved and restored by Partclone. 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. Many File systems are supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs, f2fs and nilfs2 of GNU/Linux, (2) FAT12, FAT16, FAT32, exFAT and NTFS of MS Windows, (3) HFS+ and APFS of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, (5) minix of Minix, and (6) VMFS3 and VMFS5 of VMWare ESX.
