Clonezilla live – Use this at home or for single machine backup and restore.Clonezilla works in any one of the following mode:

This software allows you to do bare metal backup and recovery. If you are looking to replace Norton Ghost Corporate Edition, try Clonezilla. You need to install partimage-server package which provides server daemon for remote imaging, much like Ghost. This provides the ability to perform an hard disk partition recovery after a disk crash. Partitions can be saved across the network using the partimage network support, or using Samba / NFS (Network File Systems). Since the partition is processed on a sequential sector basis disk transfer time is maximized and seek time is minimized. This is done for speed and efficiency, free blocks are not written to the image file. Please note that partimage will only copy data from the used partition of the partition. You can use it with FreeBSD / OpenBSD / Mac OS X / MS-Windows and so on: The dd command can make backup of any partition regardless of an operating system. # dd if=/nfs/backup/images/backup.sda1.07.28.12.img of=/dev/sda1 bs=1M conv=noerror # dd if=/dev/sda1 of=/nfs/backup/images/backup.sda1.07.28.12.img bs=1M conv=noerror You can duplicate a disk partition called /dev/sda1 as a disk image file called .dd.yy.img file: # dd if=/dev/sdc of=/dev/sdd bs=1M conv=noerror

You can clone a hard disk /dev/sdc to /dev/sdd: # dd if=/dev/sdb3 of=/dev/sdc3 bs=4096 conv=noerror To clone /dev/sdb3 partition to another partition called /dev/sdc3, enter: It can also be used for backing up the boot sector (MBR) of a hard drive or destroy data using /dev/zero or /dev/random. It copies the standard input to the standard output.

The dd command allows you to make the low-level copying and conversion of data in raw format.
