Top 6 Open Source Disk Cloning and Imaging Softwares. Disk cloning is nothing but the process of copying the contents of one hard disk (or partition) to another disk or to an “image” file. I make backup regularly using rsnapshot tool, but I also clone my hard disk once or twice a month. This option allows me to restore my OS and installed software quickly. Linux comes with various utilities for performing disk cloning.
In this post, I’m going to list my favourite open source disk cloning softwares that has saved my butt multiple times.#1: Old good dd command. The dd command allows you to make the low- level copying and conversion of data in raw format. It copies the standard input to the standard output. 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. Examples. To clone /dev/sdb.
You can clone a hard disk /dev/sdc to /dev/sdd: # dd if=/dev/sdc of=/dev/sdd bs=1. M conv=noerror. You can duplicate a disk partition called /dev/sda. OR# dd if=/dev/sda.
M conv=noerror. To restore an image, run: # dd if=/nfs/backup/images/backup. M conv=noerror. The dd command can make backup of any partition regardless of an operating system.
You can use it with Free. BSD / Open. BSD / Mac OS X / MS- Windows and so on: (Video.
Say hello to ddrescue. The ddrescue command copies data from one file or block device to another, trying hard to rescue data in case of read errors. The dd command will fail but ddrescue will continue: # ddrescue /dev/sda /dev/sdb#2 partimage – Backup partitions into a compressed image file. The partimage command backs up disk partitions into image files and restores them (much like Ghost). You can use the apt- get command under Debian / Ubuntu Linux to install the same: # apt- get install partimage.
If you are using RHEL / Fedora / SL / Red Hat / Cent. OS Linux, turn on EPEL repo and type the following yum command: # yum install partimage. Type partimage as follows to see various options: # partimage. Sample outputs: Fig.
You can now follow on screen instructions to backup or restore images. Examples. Create an image of /dev/sda. You can restore it as follows: # partimage restore /dev/sda. See how to use this fast software to backup and restore images: (Video. Please note that partimage will only copy data from the used portions of the partition. This is done for speed and efficiency, free blocks are not written to the image file. Since the partition is processed on a sequential sector basis disk transfer time is maximized and seek time is minimized.
A note about server software. Partitions can be saved across the network using the partimage network support, or using Samba / NFS (Network File Systems). This provides the ability to perform an hard disk partition recovery after a disk crash.
You need to install partimage- server package which provides server daemon for remote imaging, much like Ghost. See documentation for more info.#3: Clonezilla. If you are looking to replace Norton Ghost Corporate Edition, try Clonezilla. It provides the following features: Disaster recovery.
Disk cloning. Disk imaging. Deployment solution. Free and Open source.

This software allows you to do bare metal backup and recovery. Clonezilla works in any one of the following mode: Clonezilla live – Use this at home or for single machine backup and restore. Clonezilla server edition – Use this at office or data center for massive deployment, it can clone many (4.
Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. Fig. 0. 2: Clonezilla in action=> Download clonezilla software.#4 Mondo rescue. Another good free disaster recovery software that I use frequently. It works with Linux /Free. BSD and supports clone tapes, disks, USB devices, network and CD/DVD as backup media, multiple filesystems, LVM, software and hardware RAID.
Restoration may be done from a physical media including OBDR tape support, or CD/DVD/USB media, or from the network through PXE. This software used by Lockheed- Martin, Nortel Networks, Siemens, HP, IBM, NASA’s JPL, the US Dept of Agriculture, dozens of smaller companies, and tens of thousands of users around the world.

It runs from a bootable Linux CD image, features a GUI, and is capable of bare- metal backup and recovery of disk partitions.
It can use external hard drives and network shares. It is the simplest point and click open source backup and recovery solution available.
Any SSD cloning software works to upgrade HDD to smaller SSD? I recently bought an SSD and planned to upgrade HDD to SSD. But I was concerned that how can I safely.
You can store images on an external drive or network shares such as nfs based shared folders. Fig. 0. 4. Redo backup and recovery software in action=> Download redo backup and recovery software.#6 Trinity Rescue Kit.
Trinity Rescue Kit or TRK is a free live Linux distribution that aims specifically at recovery and repair operations on MS- Windows systems, but is equally usable for Linux recovery issues such as as rescue, repair, password resets and disk cloning. Some features: Reset windows passwords with the improved winpass tool. Full ntfs write support thanks to ntfs- 3g. Winclean, a utility that cleans up all sorts of unnecessary temporary files on your computer. Clone computers over the network via multicast. Contributed backup utility called “pi”, to automate local machine backups.
Easy script to find and mount all local filesystems. Recovery and undeletion of files with utilities and procedures. Recovery of lost partitions. Evacuation of dying disks.
And much more. Fig. Trinity Rescue Kit in action=> Download trinity rescue kit software. My favorite software. For bare metal restore I prefer dd command (gziped images) as it includes copy of the boot sector, boot partition and the root partition. The dd command works well for small setup or home users. But, for a large setup and data center, I prefer to use either clonezilla or mondo rescue softwaee due to ease of use and reliability.
