Quickly and conveniently back up your entire computer, individual hard drives, partitions, or even specific files and directories.

Why Regular Data Backup is Indispensable
Reliable data backup is often only truly appreciated after the first data loss occurs. However, a software, hardware, or user error can happen at any time and irrevocably destroy your irreplaceable data. With a backup previously created using O&O DiskImage 21, your secured data will be quickly available again with just a few mouse clicks – even if Windows no longer boots.
You save yourself the frustrating and time-consuming reinstallation of the operating system and programs, allowing you to get back to work immediately. This ensures minimal downtime and maximum operational security.
Advanced Features for Comprehensive Protection: VHD/VHDX and Fortress Mode
O&O DiskImage 21 sets new standards in data security with comprehensive support for virtual machines (VHD/VHDX). Create incremental and differential backups of virtual drives, merge them, and mount them as drives when needed. This allows you to access your backed-up files and continue working within seconds.
Another highlight of the Premium version is the unique Fortress Mode. This enables the application to run in a completely isolated and secure Windows environment. This means backups can be performed without any influence from other applications – ideal for direct forensic backups that freeze and accurately map the current state of all memory sectors of the system. Whether you integrate Fortress Mode into the Windows recovery environment or create an external boot medium, you get maximum flexibility for restoring to the original or new hardware.
Convenient Restoration
Restoring your data backup with O&O DiskImage 21 is child’s play: simply boot from the previously created boot medium (e.g., USB stick), select an existing backup, and you’re good to go. The integrated hardware-independent restoration ensures that you can transfer your old backups 1:1 to a new machine.
New hardware is automatically detected, and Windows settings are self-adjusting. If you need to access individual files due to data loss, simply load the backup as a virtual drive (also called mounting) in DiskImage and use Windows Explorer to find and copy the data – it couldn’t be simpler!
Intelligent Automation
Furthermore, O&O DiskImage 21 offers intelligent Plug-and-Play functionality: as soon as an external USB hard drive is connected, the software automatically backs up selected files and folders. This is ideal for users who tend to forget to back up or prefer not to deal with it. Once set up, everything runs fully automatically as soon as the target hard drive is connected.
You can also create a WinPE-based rescue system directly from the program onto a USB flash drive to get your system up and running immediately, even if Windows itself is no longer functional. Quality “Made in Germany. Made in Berlin.” is a maximum security and reliability.
