A disk image is usually one large file that stores a copy of a drive or an entire storage device, such as a USB or on tape. The disk image system uses compression to reduce the size of the file so it takes up much less space than the system it is archiving.
The main use of disk imaging is for backup. It is also useful as a temporary measure when decommissioning a disk. The original disk can be thrown away immediately, giving the owner time to go through the contents at a later date to look for useful and important files. Disk imaging is also used by forensic investigators to take a complete copy of an entire device for examination offsite while allowing the suspect to regain the use of that device quickly.
Here is our list of the best disk imaging software available:

A disk imaging system can also be used as a virtual drive. These are usually read-only, which is a good security feature as it means that important information can’t be damaged, lost, or altered by the users who are given access to it.
The field of backup provision has become dominated by cloud services, making disk imaging less common in business. However, since manufacturers are less inclined to include a DVD drive in their hardware these days, disk imaging can now be used to deliver software packages, which otherwise would have been shipped on a physical DVD. A disk image is useful because it acts like containerization and can hold a complete bundle of services within a secure environment together with the main application software.
Disk imaging can also be useful for organizations that need to onboard a large number of similar devices – a common setup with all of the necessary software can be stored on a disk image and copied to each new device over the network. This process can be automated, saving technician hours of work.
Choosing a disk imaging system
Although many cloud storage providers use the same virtual drive concept that is available with many disk imaging systems, these services are not usually included when listing disk imaging services. This is because, although they can give access to stored files through a mounted disk process, each file is stored individually, rather than as a complete drive compressed into one file.
Disk imaging systems are software packages for installation. Fortunately, most of these software packages are small and they operate very quickly. Although they need to be run on a host, their reach is not limited to the computers upon which they are resident. The typical interface for these systems allows the user to copy from one location to another. This can be performed across a network or even across the internet.
What should you look for in disk imaging tools?
We reviewed the market for disk imaging systems and analyzed the options based on the following criteria:
- A disk imaging system that is part of a backup service
- The option to take a snapshot of the entire disk down to the bare meta
- The ability to store images on cloud servers
- Options to selectively copy segments of a disk
- A disk imaging service that can operate across the network
- An opportunity for a no-cost assessment
- A free tool that’s worth using or a paid tool that offers value for money
With these selection criteria in mind, we have discovered some useful disk imaging services and we made sure to find systems that will run on either Windows or Linux.
The best disk imaging software
A big advantage of disk imaging software is that it isn’t considered cutting-edge technology, there are many providers in the market, and so the packages are usually very affordable.
Many disk imaging tools charge business users and allow private individuals to use the software for free. Even those packages that are charged for can often be experienced for free during a trial period. So, disk imaging software won’t break the bank. Having one of these tools on hand means that the systems administrator will always have a quick way of copying a disk at a moment’s notice.
There are many disk imaging systems available. A lot of these have been in circulation for a long time and they are very stable and not prone to virus infection. We have looked at the market and derived a list of some very solid and reliable disk imaging tools.
You can read more about each of these options in the following sections.
NinjaOne Backup is a module offered by a cloud platform that is designed to support managed service providers (MSPs). The Backup unit is available as a standalone product but it can also be used in conjunction with NinjaOne RMM. NinjaOne provides a multi-tenant architecture in all of its products that keeps the data of clients separate. The tool is also suitable for use by IT departments for in-house backups.

ManageEngine OS Deployer offers a management system for setting, storing, rolling out, and reinstalling operating systems for desktop computers. It also allows the standardization of computer settings and it stores and installs all necessary hardware drivers along with the operating system.
The OS Deployer is offered in three editions:
- Free – A full implementation of OS Deployer that will only manage four workstations and one server.
- Professional – A service for unlimited endpoints that are all located on the same LAN.
- Enterprise – A system that will roll out and manage OS to multiple sites.
ManageEngine OS Deployer is limited to working with Windows versions – it doesn’t handle macOS or Linux devices. A great feature of this on-premises software is that the Free edition has all of the functions offered in the Professional version. However, it does have a limit on the number of endpoints that it will serve.
An interesting feature is that the system is able to query the services and hardware on each device and only install and activate those drivers that it requires. So, it isn’t necessary to tailor an exact image for the entire environment for every variation of hardware configurations that you might have on site for each computer type.
- Online/offline imaging
- Multicast/ Unicast deployment
- Hardware Independent Deployment
- Computer Specific Settings
- SID handling
In summary, ManageEngine OS Deployer enables you to use stored OS images to be applied to all new devices, allowing you to standardize and automate the setup of your fleet. The deployer has smart processors that only applies drivers that are appropriate to the OS version of the device that is being set up. Better still, there is a free version of this package among its three editions. The paid versions are both offered on a free trial.
- Offers intuitive imaging and deployment without sacrificing technical customizations
- Flexible pricing – a great option for enterprises as well as small businesses
- Supports remote office deployment, ideal for multi-site organizations

One problem with selecting a disk imaging service is that most utilities either work for Windows or Linux. Acronis Cyber Project is one of the few disk imaging systems that is available for both. It is also able to operate on mobile devices running Android or iOS.
The capabilities and extra facilities of Acronis Cyber Project make it a standout product that is way ahead of the competition. The only reason this disk imaging service didn’t make it to the number one slot in this list is that it is intended for home use. It only installs on one device at a time and there is no networked version. That means that it needs to be installed on each supported PC and the technician would have to visit each machine and run the service manually in order to get an image or install it. That just isn’t practical in today’s business environment.
- Creating a backup schedule takes just a few minutes
- Great option for both home users and established businesses
- Supports mobile devices via iOS and Android app
- Is easy to use without sacrificing advanced features
- Available for Windows and Mac, a great cross platform solution
- Advanced features may take time to fully learn and utilize
Pricing Model: Small businesses that operate out of a single office would find this tool suitable. The base package, called Essential, costs $49.99. The system includes ransomware protection and anti-malware.
Download link: Acronis Cyber Project offers a 30-day free trial.
This Acronis Disk Director backup product is aimed at businesses. It can be used to create virtual drives and it runs on Windows. The tool is able to back up just about every known operating system.

Clonezilla is a free utility that is good to have on hand for emergency disk backups through imaging. The program can be run from a USB stick, which makes it possible to use it on different operating systems.
There are three editions of Clonezilla:
- Clonezilla Live – A portable version to be used for one device at a time. The program creates a bootable sector on the USB so it can be used on a device that has no operating system installed on it.
- Clonezilla Lite Server – This version operates across a network and is able to write to many devices at a time.
- Clonezilla SE – A central disk image server that is able to handle a larger number of endpoints than Clonezilla Lite Server.
Clonezilla isn’t perfect. The system isn’t capable of accessing individual files on an image and it can’t do incremental backups. It will just copy and store an entire volume or disk and write out the whole lot. The user interface is a little clunky. However, many systems administrators prefer to use the command-line utility of Clonezilla to build it into their own automation scripts.
One of Clonezilla highlights: Lightweight, and available for Linux, Unix, and macOS as well as for Windows.
- Available for Linux, Unix, and macOS as well as for Windows
- Free and easy to use
- A useful tool to have on hand for emergency disk copying even if you don’t have a policy that requires regular disk cloning.
- Open-source transparent software
- Can recover and restore to bare metal servers
- The Server version can clone up to 40 machines at once, making it a decent option for larger networks
- Must install on USB or CD after configuration for deployment
- The interface is barebones, and not intuitive for new users
Pricing Model: Free of charge.

6. EaseUS Todo Backup
EaseUS has two modes: incremental backup and disk cloning. The backup service works through the operating system to copy files, while the cloning service gets down to the hardware and copies segments off the disk. Both services have a corresponding restore system.
EaseUS is available for free, which makes it very attractive. However, this service is aimed at home users and isn’t intended to work for large businesses. There is also a paid version that has more features. This is called the Home edition and this is where the disk imaging service is available – the Free edition only has file backups. A Business edition is able to operate across a network and includes a scheduler for automated backups.
- Free tool with paid options
- Supports both incremental and differential backups
- Supports multiple recovery mediums (RAID, USB, and NAS)
- Only available for Windows
- User interface can be complicated at times
- Might not be the best option for enterprise-level replication
All versions of EaseUS Todo Backup run on Windows and the Business edition is able to back up data on other operating systems remotely. The Business edition also includes disk cloning functions. The Business edition is available in three plans and you can get a free trial of any of them.
7. AOMEI Backupper
AEOMI Backupper is available in seven different editions. One of those plans is an RMM service and all install on the Windows and Windows Server operating systems.
The headline version of the AOMEI Backupper is the Free edition. This is a nice option for home users and its use by businesses isn’t allowed. Curiously, AB Professional isn’t allowed for use by businesses either. These two editions plus the AB Workstation plan install on Windows and not on Windows Server. The AB Server, AB Technician, and AB Technician Plus plans are all written for Windows Server.
The AB Technician and AB Technician Plus plans are priced per technician and there is no limit on the number of devices that Backupper can access. These two are also more likely to appeal to midsize and large companies because they can operate over the network, while the other function on the protected device.
All options provide file backup and restore management and disk cloning and all but the free version offers protection for backup systems with encryption.
The AOMEI Centralized Backer is a multi-site system that includes multi-tenant features that will appeal to Managed Service Providers (MSPs). This plan includes the ability to serve an unlimited number of endpoints on an unlimited number of sites, so it would be good for the central IT departments of large corporations as well as MSPs.
- Supports version for home and businesses
- Offers lifetime licensing
- Provides continuous backups and incremental restorations – great for lost of deleted files
- Only available for Windows
AOMEI offers a 90-day unconditional money-back guarantee on all of its paid plans.
8. Macrium Reflect
Macrium Reflect provides disk imaging and backup/restore. The base version of this tool is the Free edition. Businesses are allowed to use those free tools. It needs to be resident on the computer that it is imaging. However, you could just download many free copies if you have several endpoints to protect.
The software installs on Windows and it can back up a live OS onto a USB stick that includes a boot sector. This enables technicians to set up a PC with all allowed software, take an image, and then use that copy as a standard setup for all new PCs.
There is a Server edition that runs on Windows Server and also networked solutions for larger businesses with many endpoints to manage. Site Manager covers one network and Macrium Multi-Site includes remote management features.
Macrium Multi-Site is a cloud service, hosted in Azure. This also has multi-tenant features that make it suitable for use by MSPs.
- Can rapidly compress machine data into image files for easy access or reinstallation
- Supports living imaging, allowing it to backup during working hours
- Can backup virtual disk drives in Hyper-V
- Enterprise pricing is a bit high compared to similar tools
- Designed for technical users, not ideal for those new to backup software
All Macrium Reflect products are available on 30-day free trials.
SmartDeploy offers a central console from which businesses can manage endpoints. The systems administrator adds an endpoint into the service, which gets an agent program installed on that device. From that point, it is possible to take a disk image or copy over a saved image to a new machine. Images can be stored on a local device or a cloud server.
This is a little more than a disk imaging system because the service provides a library of applications that can be installed on network devices. It is possible to create a standard setup and then roll it out to all devices, storing a record of that package instead of a disk image so that it can be set up quickly on new devices.
The system is available in three editions: Basic, Essential, and Premium. Integration with cloud storage is only offered in the Premium plan. All plans include disk imaging and the upper two plans allow control of disk imaging activities over the network and the internet from one central location. There are no limits on the number of endpoints that can be managed with any plan.
- Combines asset management with disk imaging and backup
- Supports unlimited endpoints
- Can deploy apps, manage drivers, and orchestrate Windows updates
- Is a “Jack of all trades” – not ideal for those looking strictly for disk imaging
SmartDeploy is available for a 15-day free trial.
10. Paragon Drive Copy Professional
Paragon Drive Copy Professional is part of Paragon Hard Disk Manager. This tool supports the resizing of partitions and backup to a USB stick as part of its disk cloning functions. The toolkit also provides a bootable disk or stick to access damaged operating systems and recover files with its Recovery Media Builder.
The USB stick version of the tool creates an entire copy of all of the files of a PC that can be operated from anywhere by plugging that USB into another computer. The system supports the creation of secure virtual drives over a network.

Three of the other four editions include disk imaging. The lowest of those eight plans is Free. This includes an automated incremental backup service but it doesn’t have a disk imaging utility.
Disk imaging is included with the Desktop, Essential, and Full editions of Iperius Backup. These systems all install on Windows or Windows Server. These plans can all be managed by a central console although the backup software needs to be installed on each protected endpoint.
Disk images can be sent to cloud storage systems and Iperius also offers its own online storage service. Other utilities included in the Iperius Backup service are the Iperius Recovery Environment, which is able to access damaged operating systems and reassemble shattered files. All plans include compression and encryption of disk images. The image taking and loading can be automated and operated over a network.
- Supports integrations into cloud services like Google Drive, OneDrive, and Amazon S3
- Automatically encrypts backups using AES-256 bit encryption
- Supports database formats like MySQL and PostgreSQL, making it a solid choice among DBAs

Disk imaging FAQs
What is disk image software used for?
Disk imaging software has many uses. It can be used to store a standard setup for onboarding new devices and it is also regularly used by law enforcement to make copies of the computers of suspects for forensic investigation. A disk image takes a snapshot of a computer, storing all software as well as data.
How does having a disk image reduce the problems of total software reinstallation?
Set up a computer with all of the software you want that user role to have and then make a disk image. That image can then be applied again and again to create a standard profile for user devices. You can then guarantee that every computer is set up the same and onboarding devices can be implemented with automated processes.
How do you open a disk image software?
In order to open a disk image and look through it, you need interpretation software. The process of making a disk image accessible is called “mounting.”
