9 Useful Free and Open Source Disk Imaging Software

System crashed! One of the worst fears of businesses is what if their system crashes suddenly? What if the hard drive that has an enormous amount of valuable data in it corrupts suddenly? Remember the infamous JournalSpace data loss (2009) blunder. JournalSpace was a six-year-old blog hosting company that reported the operating system crash with no back-up data in place for recovery. It affected the company and hundreds of bloggers who hosted their site on JournalSpace. The company had to shut down. Spending 6 years on building a company with hundreds of bloggers on the platform to end like this is tragic. But wait, even worse, was the Microsoft Sidekick's cloud server data loss (2009) that resulted in 800 thousand customers losing their contacts, photos, email addresses, and to-do lists. It cost Microsoft a huge amount in compensation and people's faith in cloud computing was shaken to the core.

Such incidents, whether they occur due to human errors, viruses or malware, hacker activities, hard drive corruption, power outages, theft, or disasters such as fire or earthquake, point towards the need for companies to keep multiple back-ups at multiple locations for complete data security. Everyone requires some kind of back-up in life; even militaries can't do without it. Companies need to have a proper back-up strategy to restore the data in case of an adverse happening.

Disk Imaging and Disk Cloning are two ways in which businesses, large organizations, government institutions, and even individuals can keep the back-up of their valuable data. Both Disk imaging and Disk cloning serve the same purpose, with a slight difference in their methods to do so. Both have the same goal, and both have software and hardware requirements to complete the task. One deploys a disk imaging software and the other a disk cloning software.

What is Disk Imaging/Cloning?

Disk imaging is the computer system process by which an archive is created for a source disk, which can be later used for making more copies of the hard drive. In the Disk imaging process, all the data of a hard disk is copied sector-wise, including hidden files and configurations. This data is copied to another hard drive in a compressed form. It allows more than one image to be reproduced on a hard disk so that users can take back up of more than one computer into the destination disk. The image has to be restored and installed on another computer to start working. Disk imaging software creates an archive of the source disk that can be used to create a back-up copy of the source disk.

Disk Imaging Software

Disk Cloning is a process by which one hard drive is copied into other drives to make an exact copy of the source drive. A clone will have all the contents from the source drive, but it is not in a compressed form. Once a clone is formed, users cannot add or change data. A clone is ready to use a disk that can be inserted into any computer, and it will start working. Disk cloning software creates a clone of the source disk into another hard drive.

What is the difference between Disk Imaging and Disk Cloning?

Difference between Disk Imaging and Disk Cloning

 

Who Uses Disk Imaging Software?

  1. Corporate World

Small and medium-sized businesses, large scale companies, and conglomerate corporate organizations use this software for back-up and other purposes. Mostly they prefer a Disk Imaging Software that provides cloud services along with the Disk imaging or cloning service. As these companies have considerable data to monitor and store, they always require a disk imaging solution provider who takes care of the entire data section.

  1. Government Institutions:

Present-day Governments are creators of bulk data. The data about their various departments, branches, citizens, and sensitive defense data has to be stored carefully with multiple back-ups. These institutions use the service of a Disk imaging solution provider to create a back-up on a large scale.

  1. Forensics Department

The use of this software is not only limited to the corporate world, government organizations, individuals, but other entities like forensics departments and data recovery firms also use this software for various purposes. In Forensics, this is mainly used to create a back-up of electronic evidence like computer hard disks, mobile hard drives, CDs, Floppy disks, Camera memory cards, etc. As the original evidence cannot be tampered with in legal proceedings, so forensic experts first create an image and then run all the tests.

    Data Recovery Firms

      Data recovery firms that recover data from even damaged hard disks use high-quality disk imaging software to complete the process. Mostly these firms are employed by Government departments, the forensics department, corporates, and sometimes even individuals reach them to recover their deleted, damaged, or corrupted data.

      1. Individuals

      Individuals in professions like chartered accountancy, specialist doctors, stockbrokers, real estate consultants, counselors, and others create data that they require to be safe and secure. Deletion or damage to such data can cost them a lot. They utilize Disk imaging and cloning software services to help them create a back-up for their data.

      Uses of Disk Imaging Software

       

      What are the features of Disk Imaging Software?

      • Supports all file formats

      A disk imaging software should be able to copy all types of files and extensions. It must also copy files that have a long name.

      • High speed of work

      The processes, such as disk imaging and disk cloning, take a lot of time. The kind of data that they back-up is too massive. There are chances of errors also. The software that exhibits a high level of speed to accomplish this task is always preferred.

      • Encryption

      Uploading data for back-up to hard drive or cloud servers comes with the risk of intrusion. The hackers and malicious viruses might try to interrupt the service or steal data during the transfer process. Most of the disk image software comes with inbuilt encryption. Encryption protects important data.

      • Boot disk option

      The disk image is too big and takes a lot of space. So external hard drives are used to take back up. This back-up has to be loaded back to a computer. This requires a boot disk. The boot disk is a disk or temporary set of files that are needed to install or boot a computer to load an operating system.

      • OS imaging

      The term means to capture the images of one system and then to replicate it on other. The whole operating system is copied by IT administrators and is run on others.

      • Disk Cloning

      Most of the Disk imaging software can also be deployed for disk cloning. This software will have this feature mentioned outside. Clones disks or partitions of different sizes.

      • Remote Imaging

      Sometimes administrators might not have physical access to computers that they want to image. Remote imaging allows imaging a distant computer remotely.

      • Scheduling

      Users can schedule and set the regular time intervals at which they want the disk imaging software to start disk imaging automatically. Sometimes users forget to take data back up for many days, and their data is vulnerable to lose or attack. Scheduling will ensure that data back-up keeps happening on its own at regular intervals.

      • Cloud back-up

      The disk imaging software has the capacity to upload data to cloud servers directly. A cloud back-up of the disk would upload the source disk data into cloud servers owned either by the disk imaging software company itself or some other third party vendor that provides cloud services. It is a practical solution to put all data into the cloud as generally, the data created by businesses is too huge for the disk drives. This happens in real-time, so in case of a system malfunction, the data is safe, and there is a negligible loss of data. Not all disk imaging software provides this service, but most of them do.

      • Differential Back-up:

      A disk imaging software should be able to compare two disks together and find the difference. It should then take the back-up of the difference only.

      • Simple Interface

      The software should not be too much complicated for users to understand. Intuitive software that is easy to use is preferred.

      • Partition Management

      The software manages partition related issues also. It can change the disk volume utilized by each partition of the disk.

      • Incremental Back-up

      The disk imaging software should also be able to take incremental back-up. Incremental back-up is an addition to the already existing back-up of a disk. If changes were made to the source disk and additional content was added, then incremental back-up would take only the newly added content for extra back-up. This makes a lot of sense.

      Conclusion:

      Today technology is evolving at speed never witnessed before. Up-gradation and updates in both hardware systems and software capabilities have become a norm. Companies have to stay abreast of this by constantly monitoring their own systems and then timely upgrading the same. Companies can't even afford a slow hard disk that takes time to install data. When it comes to technology, the transition is from hours to minutes, minutes to seconds, and seconds to nanoseconds. For instance, many stock market companies spend millions of dollars just to be ahead in nanoseconds in receiving the ticker information. They can't afford any glitch, downtime, or loss of data. Their servers must always be running. There should be multiple back-ups available instantly.

      Disk imaging and Disk cloning software play a vital role whenever companies need to update their systems. As new hardware and software installation process come with its own risks, it is always prudent to first take a back-up of everything that you have. In case of any installation errors or failure, the back-up is the only way to help you restore all systems in the status quo. In short, businesses cannot afford the grave mistake of not investing in such technologies and software.
