DiskImage 20 Usability
In this section I will share my hands-on experience with the latest version of O&O Software’s DiskImage 20 backup software. I will walk through the download and installation process before exploring the many data backup, disk imaging, data recovery plus dedicated disk cloning and system migration features.
This process begins via the official O&O Software website where a full 30-day free trial of DiskImage 20 is available (no account is required for making use of this trial).
Installing DiskImage 20
Installing DiskImage 20 begins via the official O&O Software website where a fully featured 30-day free trial version of the software can be downloaded.

Despite initially being a fast download at just over 2MB in my own instance, the installer then went on to download a further data meaning an active internet connection is required throughout the installation process. Once downloading was complete the installer allows either a typical, complete or a custom installation to take place (as can be seen above) installing only required components as requested.

With the installation process complete, the software will ask that it is activated (for those already having purchased a licence key) or that the 30-day free trial be activated (which can be done form this same page in the installer application). Somewhat disappointingly, a restart of my PC was required after activating the software for myself before the installation was then fully complete and ready for actual use.
NB – Remember, O&O Software offer a full 30-day free trial of DiskImage 20 should you wish to try this backup software out for yourself (also note that O&O require no personal nor payment details to take advantage of this trial).
Making One-Click Disk Image Backups
One of the key features of DiskImage 20 is its ability to make full disk image backups of a Windows PC. Disk imaging is a special type of backup which sees the entire contents of a PC (inducing the operating system, documents, system settings plus any installed software) automatically included and backed-up as a part of the process.

NB – Disk image backups are more comprehensive than file-level backups, albeit at the cost of usually running slower and taking up more storage space in the process. For a full and detailed comparison of the two methods, please refer to this specialist disk image vs file-level backups guide right here on BestBackupReviews.com.
Creating an initial disk image backup is really easy within DiskImage 20 thanks to the simple “One-click Backup” module. Available via the main application homepage, this easy-to-use tool with just a click (or two) will allow for a full disk image backup of all attached disks to be made and stored in the default target storage location.

As can be seen above, the One-click module does allow for additional options to be set via the “More Options” menu as well as a custom storage location be configured for saving the backup to if this is required. Additional options available here include being able to automatically convert the disk image to a universal format (VHD or VHDX format), set a comment describing the backup or set the device to shut itself down after the operation is complete.

Once complete, a summary page will be shown and the disk image itself will be saved as a “.omg” image file format by default (unless the use of a VHD or VHDX was specified during the configuration process). From this point onwards this file can simply be stored safely as a backup of the entire PC or, as will be seen later on in this review, used as the basis for making further incremental or differential backups providing continued system protection.
Making Disk Image Backups (Advanced)
Whilst the one-click disk imaging module is without doubt one of the easiest ways of making an initial full disk image backup, the DiskImage software provides additional and more advanced disk-imaging functionality for anyone requiring such functionality. Automatically scheduled disk image backups form a key feature of the DiskImage offering as do other advanced features including secure AES 256-bit encryption, compression, incremental and differential backup methodologies, custom historic versioning plus sector-by-sector disk imaging amongst other available features.

Beginning at the “Drive operation” tab is where the disks to be included within a disk imaging backup can be selected (see above) and, via the “Options” button found on the menu bar, the specific configuration options set. Once on the options page (see below) we can manually specify backup settings or, if available, simply select an existing profile from the profile menu with pre-existing settings then applied.

As can be seen above, DiskImage makes it straightforward to specify the disk image file format being utilised, the level of data compression applied, manual file splitting parameters (useful for when saving onto fixed size media such as CD/DVDs) as well as being able to specify between 128-bit and 256-bit AES encryption.
NB – Remember, once set, these settings can be saved as a profile within the DiskImage software making re-use of these same settings quick and easy next time they are required (they can also be exported and imported when working across two or more devices).
Once the backup set is started (via the “Backup” button found at the bottom right of the page) the same summary screen as was seen earlier on (during the one-click backup) will be shown and the backup set can begin working.

Upon completion of the backup the application will (again) show a summary page detailing the result of the operation and the disk image file (again, a “.omg” format) will be saved onto the target storage. Moving forwards and this disk image file can now become the basis of a scheduled and incremental disk image backup via use of the “Jobs & Reports” page as can be seen below.

There are two main methods for making a scheduled backup job within DiskImage 20, this includes a wizard-based approach plus the ability to manually configure all required options if more exact settings are required.
Starting off with the wizard-based method (I will cover the manual approach later on) and a new job can be created by clicking the “Start wizard” button found on the main menu before being greeted by the initial setup page which will ask for the backup type to be created.

The wizard seen here can be used to create full disk image backups however, since I have already followed this process earlier on, I will set-up this wizard to simply focus on creating incremental image backups based upon this existing full disk image.
NB – As far as I can make out, the DiskImage job configuration process does not allow for handling both the making of an initial (base) full disk image followed by incremental image backups in one go. This means (as far as I can work out) it is better suited to simply crating an ongoing incremental imaging job when working from an existing base disk image.

The next step in configuring this automatic backup job is the selection of a schedule. This process is unfortunately limited to a maximum frequency of once per day as can be seen above (although it should be noted this job can be set to run upon the connection of a specified drive or run manually whenever required).

The next page, given I am creating incremental backups here, is where the base disk image file (see above) can be specified (the password must also be entered here if one is set). After specifying the base disk image file, the target storage location can then be specified as can the file naming format which makes easy the adding of date and time values via pre-set variables (should this be required).

Moving on to the next page in the wizard and this is where some very important settings including compression, encryption, overwriting rules, maximum file sizes and historic versioning can optionally be set. Compression and encryption can be turned on individually (the software will prompt for a password once checked) and the historic versioning history is effectively set at this point by specifying the maximum image file count (meaning if you set a maximum of 30 files here and make a daily incremental backup then it will (effectively) provide 30 days of historic versioning).

Once complete, the configuration wizard will show a summary of the new job and the job itself will also become visible in the “Jobs & Reports” tab as can be seen just above. At this point I can simply wait for the schedule to start the job when it is time to or, by right-clicking on this job, choose to run it on demand.

Once the job has completed its work a summary page will be displayed and the report, along with any others for this job, will be saved and become viewable (as can be seen below).

With this new job now configured and running as intended, there are still a couple of things to point out relating to these jobs within DiskImage 20. Firstly, these jobs can be edited if any changes are required by simply selecting the job and clicking on “Edit” from the toolbar. We also have the ability to export jobs and save their configuration details (as XML files) should there be a requirement to move any pre-configured jobs between different workstations running the DiskImage software (or simply to act as a backup of the job).
Making File-Level Backups
Whilst DiskImage 20 undeniably provides some good disk imaging-based backup options, also available are file-level backups as well. These file-level backups focus on backing up only selected files and because of this can often prove a faster and more disk space efficient option versus disk-imaging when the full coverage of a disk (e.g. everything including the operating system) is not required.

As can be seen above, creating a file backup begins by simply selecting any files and folders to be included in the set. Once all files and folders are selected, clicking the options button will allow any advanced options to be configured in much the same way as was done when configuring the disk image backup earlier on.

File-level backups made within DiskImage 20 can take advantage of multiple encryption options (up to and including highly secure AES 256-bit encryption), strong data compression plus the ability to automatically split resultant data files into specified sizes for easy storing on fixed size media (e.g. 4.5GB sized files can be specified for storage on regular DVDs). As was the case when making image-based backups earlier on, these settings can be saved to and loaded from a profile meaning they can easily be used across multiple backup sets or even exported and used across DiskImage installs across multiple devices.

Once all configuration options are set, the pre-run configuration box shows the finalised settings upon which the backup will be run and also allows for specifying the disk and location to store this backup. Once complete, DiskImage will make use of the same style of summary report to show the results of the file backup operation and to notify the Windows user of any errors and issues when applicable.

When configuring an automatic backup job earlier on (for the disk image backup) I made use of the wizard interface which guides users through the entire setup process, this time I will click on the “Add as job” option to configure this job manually. As can be seen above, this begins by selecting the “File backup” option before then selecting the “File backup of the changes” option on the following page.

Having now configured and initially run this new automatic backup job, we can now head back to the “Jobs & Reports” tab to look at the interface which allows for editing existing jobs within DiskImage.

As can be seen above, when manually editing a backup job we have the ability to make all changes which might be necessary. This includes being able to configure a schedule, rename the job and add notes, specify the data file name (with date / time variables when required), specify any tasks or commands be run on the device before and or after the job has completed and also specify the maximum number of data files to be stored (effectively enforcing the historic versioning settings by doing so).
NB – Remember, O&O Software offer a fully functional 30-day free trial of DiskImage 20 should you want to try out any of these backup features for yourself.
Restoring Data within DiskImage 20
Having now seen both disk image and file-level backups configured and in-use within the DiskImage 20 application, I will in this section be looking at the options provided for recovering such backed-up data. Starting off with the file level backup set configured in the previous section and recovery here begins in the “File operation” screen where a backup file can be selected to recover from.
NB – When selecting the file, be sure to select the correct date of file if you require recovery of data from an older version of the backup.

With the data file selected (and the password entered, if necessary) it will be possible to browse all files included within this backup set and select those which are to be recovered. After selecting such files, we can then choose the restoration location manually in the next step, something which is nice to see versus being forced to recover files to their original location which is the case with some other backup tools.
NB – When installing and configuring new backup software, always perform a test restoration of any backed-up data (for real) to ensure everything about the process is understood and that the backup is working as you might expect.
Moving on to the recovery of disk image backups and we have two main recovery options available within DiskImage 20. One option is mounting an image backup file as a virtual drive within Windows (which can then be used for browsing any files we wish to recover) and the second option which involves restoring the entire disk drive which has been backed-up to an earlier state.
NB – When recovering an entire disk, we are limited in that we cannot recover the disk which has the active OS installed upon it whilst actively in-use. In such cases where we need to recover the working (in-use) operating system disk, we must first boot into the DiskImage 20 recovery environment (which can be created within the DiskImage application itself).
Starting off with the virtual drive mounting approach and we can find the necessary Windows drive mounting tool under the “Tools” tab to begin.

As can be seen above (via the drive mounting tool) we can select the necessary disk image data file to be mounted and then (optionally) select to mount the entire drive or just a single partition upon it (note that we can also specify the drive letter which will appear in Windows should we need to). Finally, clicking on “Mount drive” will perform the actual drive mounting operation and, once finished with the drive, it can then be unmounted by simply right-clicking on the drive within the Windows explorer and via the context menu selecting the unmount option.
Finally, should we need to recovery the entire system or the currently live system disk (e.g. due to hardware filature, malware issues and similar), then it is possible to create a bootable system recovery disk from within DiskImage itself. This starts by having access to the DiskImage bootable recovery media which can be created via the “Create bootable disk” button found (again) on the “Tools” menu as is seen below.

Not only can DiskImage be used to create a physical boot disc, but also a recovery partition on an existing disk as well as a bootable USB flash drive as well (all options require the WinPE environment be installed first and, if this is not the case then the tool will guide users through the process). Once the recovery disc (or other media) has been created, the system can be booted into the DiskImage recovery environment as can be seen below.

The DiskImage recovery environment contains the DiskImage software itself (which can be run from the desktop once this bootable environment is running) and allows users to configure the environment (including setting an IP address) during the boot-up process. Once open, the DiskImage software runs in much the same way as the fully installed version does in the regular Windows system meaning we can recover the system disk (in this example) by simply navigating to the “Drive operation” tab, selecting the image file to be used and then confirming the source and target disks to be reimaged.

From this point onwards, this live version of DiskImage will perform the disk recovery operation in much the same way as it would when using the installed desktop version (albeit allowing reimaging of active system disks when working from within this bootable media). Upon completion, the software will prompt as to whether or not to make the newly reimaged disk bootable and the system can then be rebooted into this recovered disk as normal completing the recovery process.
Disk Cloning within DiskImage 20
With the core data backup functionality aside, another really useful aspect of DiskImage 20 is that it also contains a dedicated disk cloning utility which helps to make direct disk-to-disk cloning operations possible.

As can be seen above, the dedicated disk cloning tool (accessed via the “Cloning button” on the menu or the app’s homepage) begins with a straightforward page where the source and destination disks (or individual partitions) for cloning can be selected.
NB – Should you prefer, this disk cloning tool can be also used via the DiskImage bootable media solution (meaning a disk can be cloned without having to first boot into Windows). Ideal for times when a PC or laptop wont boot and the entire system must be backed-up.
Having selected both source and destination disks, advanced options for the cloning operation can be specified by clicking on the “Options” button found on the main toolbar.

DiskImage 20 provides plenty of advanced disk cloning options which can (in the same way as can be done with disk image and file-level backups) also be saved to custom profiles making them both exportable to other devices and easier to recall next time they are required. Key options available here include locking the source drive prior to cloning, skipping and excluding any bad disk sectors on the disk plus the option to specify excluded files and file types amongst various other options.
NB – The DiskImage cloning utility also supports cloning only used disk sectors for faster operations or one of two forensic cloning modes which means all sectors on the physical disk will be cloned to the target (even if they are not currently active or populated with data).

Before cloning commences, DiskImage will provide a summary of the cloning job to be undertaken and (if applicable) also offer to set the target disk drive as bootable if the source drive is also bootable. One cloning is complete a summary screen will be shown detailing any relevant information and (if present) any issues and errors encountered.
Furthermore, thanks to the inclusion of Machine Independent Restoration technology (M.I.R), the DiskImage disk cloning module also supports cloning to disks which will ultimately be used on new (or different) PCs when this special option is invoked. This means the cloning tool is not only ideal for updating an existing PC to a new disk (or SSD drive), but also for migrating an existing system over to completely new hardware.
NB – DiskImage 20 will automatically detect if either mechanical or SSD drives are used in the cloning process and automatically optimise for 4K sectors as required.
Other Tools & Features
So far, we have seen the core backup, disk imaging and dick cloning capabilities of DiskImage 20 and how the software handles such tasks both as an installed application or via use of the bootable recovery environment. Core features aside, in this section I will be highlighting some of the additional tools and functionality DiskImage 20 has on offer.

The “Tools” tab (see above) is where the majority of the additional tools and modules included within DiskImage can be accessed. This includes the virtual disk mounting tools for mounting disk image backups and even supports mounting ISO format files as drives (with a drive letter assigned) within Windows. Also included here is an easy-to-use tool for mounting and dismounting network drives via the DiskImage application, something which can be done within Windows itself, although a task made a little more user friendly thanks to the interface which is provided here.
With some other smaller utilities including being able to view and validate disk image files set aside, two of the main tools remaining on this page are the disk image file converter and the disk image file merging utility. Whilst the image file merger simply consolidates multiple image files (i.e. versions) into a single file saving space, the conversion tool is especially useful as it supports conversion from a DiskImage native OMG file into a Microsoft standard VHD or VHDX format.

As can be seen above, converting a file format type is as simple as first selecting the source disk image file and then the target format. When applicable, other settings can also be applied including encryption and data compression during this same process.
DiskImage 20 Security
One of the most important methods of ensuring any backed-up data remains private and secure is to make use of strong encryption technology in combination with a strong password whenever creating backups.

Thankfully, DiskImage 20 provides support for applying highly secure, zero-knowledge encryption (with up to AES 256-bit encryption technology available) across all disk image and file-level backups made within the software. Turning on this protection is as simple as clicking a button to enable encryption when configuring a backup set and then entering a strong password before the backup is first set running.
NB – If you do decide to make use of encryption when backing-up (and it is recommended that you do) then you must remember the password which has been set. If you forget this encryption password, O&O Software themselves won’t be able to reset it and this could result in an unusable backup set and data potentially being lost.
Software Support from O&O Software
O&O Software provide a detailed support portal providing detailed coverage of the DiskImage 20 application. Support available here includes both PDF and web-based versions of the DiskImage user manual alongside various “how to” articles plus a useful FAQ section explaining how to get the most out of the backup process.

Should further support be needed, the O&O Software support team can be contacted via an online messaging system found on the main support section of the O&O website.

O&O DiskImage 20 Review Summary
DiskImage 20 performs well as a Windows backup application offering full and incremental disk image backups, one-click disk imaging, dedicated disk cloning tools plus a good set of file-level backup functionality for making more performance optimised backups. Support is provided for several key features including strong AES 256-bit encryption, potentially unlimited historic versioning, SSD 4K alignment, data compression, VHD and VHDX file formats plus automatic job scheduling amongst various other options.
Whilst the application is (on the whole) of a fairly nice design and well laid out, I believe usability and functionality could be improved in some key areas. This includes being able to set scheduled backups more frequently than just once per day (I think at least hourly would be better), official integration of popular third-party cloud storage providers into the application plus being able to configure incremental backups without having to first take a full disk image (separately) beforehand.
Pricing is also a big positive of DiskImage 20 with O&O Software offering some very competitive options beginning at $49.95 for a single perpetual licence or just $69.95 for a 5x PC perpetual licence with subscription options also available in the form of the O&O PowerPack suite (of which DiskImage 20 is a part) beginning at $4.99 per month.
Overall, DiskImage 20 is a solid and dependable Windows backup application with a powerful set of disk imaging and disk cloning features which will appeal especially to power users – Great work O&O Software.
