What does O&O DiskImage 20 Pro do?

It creates images of whole drives, single partitions, or selected files and folders that can be restored after data loss. A one-click image captures the entire computer, including the operating system, installed programs, and settings, while file backup targets only chosen data. Incremental and differential runs record only what changed, so follow-up backups finish faster and use less space. Images can be mounted in Windows as a virtual drive to browse their contents, and the included boot medium restores a system even when Windows no longer starts.

What is the difference between the Professional and Server editions?

The Professional edition images desktop Windows systems for personal or commercial use, but it is not suitable for server operating systems. The Server edition includes every Professional feature and adds support for server operating systems, multiple-OS environments, advanced network backup settings, and server-optimized performance. If you only protect desktop or notebook PCs, Professional covers the full imaging, cloning, and restore workflow. If you need to back up a machine running Windows Server, the Server edition is required.

Can O&O DiskImage 20 Pro restore a backup to a different computer?

Yes. Machine Independent Restoration (M.I.R.) adapts an existing image so it boots on hardware that differs from the source machine, automatically detecting the new system and adjusting or loading the required drivers. This is the function you use to migrate an old PC to a new one, or to bring a system back after a mainboard or full-hardware failure. The restore runs from the included Windows boot environment, so the target machine does not need a working Windows installation first. M.I.R. is part of the Professional edition, not a separate add-on.

Does O&O DiskImage 20 Pro support disk cloning and SSD migration?

Yes, it includes a dedicated cloning tool that copies a drive 1:1 onto another disk, with support for SSDs, GPT disks, and current UEFI configurations. This lets you move a Windows installation from an HDD to a faster or larger SSD without reinstalling the system or reactivating programs. Beyond cloning, images can be converted to VHD and VHDX virtual disks and mounted, so a backup can also be used inside a virtual machine for testing. Cloning works at the drive level, so it is the fastest route when your goal is a direct hardware swap rather than a stored archive.

What technical limitations should users know before buying?

The main limitation is that the Professional edition does not back up Windows Server operating systems, advanced network server backup, or multiple-OS server environments; those require the Server edition. It is a Windows application, so there is no native client for macOS or Linux. On the positive side, commercial use on desktop and notebook PCs is permitted, so a business does not need a different license class just to protect office workstations. Before buying, confirm that every machine you plan to image runs a desktop version of Windows rather than Windows Server.

Frequently asked questions about O&O DiskImage 20 Pro

Can I restore single files from a full disk image?

Yes. You can mount a disk image as a virtual drive in Windows and browse it like a normal disk, then copy out only the files you need without performing a full restore. This is useful when you deleted one document but do not want to roll back the entire system.

Can O&O DiskImage 20 Pro create a backup while Windows is running?

Yes, it creates system images during operation, so you can keep working while a backup of the running system is written. This live imaging captures a consistent state of the drive without requiring you to shut down or boot into a separate environment for routine backups.

Which Windows versions does O&O DiskImage 20 Pro support?

It runs on Windows 11 and Windows 10, and images made with earlier O&O DiskImage versions can still be opened and restored. There is no native macOS or Linux edition, so it is intended for Windows desktop and notebook environments only.
