Free Hard Disk and Partition Imaging and Backup Software

The hard disk and partition imaging software take a snapshot of your hard disk so that you can restore your system at a later time to the exact same state the system was when you imaged the disk or partition. This is useful for system recovery in case of a hard disk disaster. The term "image" is used because such software often copy the state of the hard disk sector by sector to your image. Hence if your hard disk was (say) defragmented with certain software occupying certain sectors when you backed up, it will be returned to that same state when you restore your backup. The image utilities often do not allow fine control what you backup - you can specify the partitions or hard disks to back up, but you usually will not be able to specify which folders to exclude or include. They are useful for backing up your system drive or partition, that is, the drive that you placed your operating system on. Hard disk imaging software are sometimes also used to clone a hard disk to another (useful for the times you change or upgrade your hard disk).

On the other hand, the hard disk, folder and files backup software listed here allow a finer control over what you back up. You can selectively backup and restore (say) your documents and email while omitting other files and directories. Some of the utilities allow you to schedule your backups, so that you can be sure that your important data are backed up periodically (for example, daily, weekly, monthly, etc). Depending on the utility, it may or may not support the backup of your system drive (the drive you booted from).

Note that commercial equivalents of backup and imaging software, like Acronis TrueImage (free trial download here), Terabyte Unlimited's Image for Windows, (free trial download) and Drive Snapshot are not listed below.

It is run from a bootable diskette, and is useful when you want to transfer everything from one hard disk to another as you might want to do when you buy a new hard drive to replace an existing one. It supports DMA transfer, which speeds up the rate at which your data is transferred. It works independently of the existing file system or the number of partitions the drive has.

PING - PartImage Is Not Ghost

PartImage, or Partition Image, is a Linux/UNIX utility to make an image of your partitions in a file. It is able to image only used portions of the partitions saving time and space. The images are compressed. The utility supports the ext2fs, ext3fs, ReiserFS, FAT16, FAT32, HPFS, JFS, XFS, UFS, HFS, and NTFS file systems. This is a live ISO that you can burn onto a CD so that you can use it on any computer regardless of the operating system that is running.

SelfImage

SelfImage is a utility that allows you to make an image of a hard disk partition or an entire hard disk and restore the image back to a partition or hard disk. Other features include the ability to make an image of a partition that is currently in use, as well as make an image of a partition that is not mounted, or one that Windows does not even recognise (like Linux partitions). It is also able to compress the images it makes. It saves space in your image by skipping unused sectors. Another interesting feature is its ability to make an image of disks on remote machines and restore back to them. SelfImage runs on Windows, and is released under the GNU General Public License (GPL).

Forensic Acquisition Utilities

This is basically the Windows version of the well-known (and versatile) Unix "dd" utility, which allows you to copy every sector from a device to a file (or vice versa, or from one device to another, etc).

NFGDump

nfgdump (NTFS-FAT-Generic dump) is a Windows and Linux tool that dumps (images) and restores NTFS, compressed NTFS, FAT16, FAT32 and any generic partition. Dump files (that is, the backup image) can be compressed, encrypted or split. The page file can also be omitted from the dump file / backup image. The software is released under the GNU General Public License (GPL). It runs under Windows 2000, XP and Linux. This is a command line program.

WinDD

This is a Windows version of the well-known (and versatile) Unix "dd" utility. It runs on Windows XP and is released under the GNU General Public License. This is a command line program.

DriveImage XML

DriveImage XML is a hard disk imaging utility that allows you to backup a PC's hard disk or partition from within Windows XP (XP Home and/or XP Professional only). It can image a partition that is currently in use (such as the system drive), compress the image while backing up, restore an image to another partition/drive and clone a drive. Note that although it is able to image the system drive while you're working in it, it cannot restore the image to the system drive if it is currently in use (obviously). The solution is to use their BartPE plugin (what they call the "WinPE boot CD-ROM") to create a BartPE CDROM. You can then restore your system partition after booting from the CDROM. See my tutorial on How to Create a Bootable "Live" Windows Rescue CD for more information on how to create such a CD.

g4u - Harddisk Image Cloning for PCs

g4u is a bootable CDROM, or if you prefer, floppy, that allows you to clone an image of a PC's hard disk for deployment on other PCs using FTP. The bootable floppy and CDROM supports both the cloning and restoration process. g4u supports any operating system on any filesystem. All you need are two floppy disks or one CD-R/RW, an FTP server and a DHCP server. The bootable disk uses a NetBSD system.

Partition Saving

Partition Saving is an MSDOS hard disk imaging utility. Place it on an MSDOS boot disk and use it to image your Windows, MSDOS and Linux partitions. It supports the imaging of NTFS, FAT32, FAT16, FAT12, ext2 (and possibly other) partitions. It can do a sector-by-sector copy or (for the partition-types listed here) copy only the occupied sectors thereby saving space and time in your backups. It is able to automatically split the backup file into smaller files of a size you specify (useful if you plan to burn the backup to a CDR(W) or DVD+/-R(W) later). The backup file may be compressed with a compression level you select. Updated: starting from version 3.50, Partition Saving now works in Windows and can be placed on a BartPE Rescue CD.

PartImage

PartImage, or Partition Image, is a Linux/UNIX utility to make an image of your partitions in a file. It is able to image only used portions of the partitions saving time and space.
