O&O DiskImage is a professional backup and disk imaging software for Windows, enabling users to create complete system images, back up individual drives or files, and restore them even to different hardware. It is developed by O&O Software GmbH and available in several editions for home users, IT professionals, and enterprises.

Core Functions
1. Backup & Imaging
- Full System Images: Creates bit-by-bit copies of entire drives or partitions, capturing the operating system, applications, and all data.
- Incremental & Differential Backups: Saves only the changes made since the last full image, saving storage space and time.
- File-based Backup: Allows backing up individual files and folders, not just entire drives.
- Forensic 1:1 Copies: Creates sector-by-sector copies including empty sectors for forensic analysis or advanced data recovery.
- Hot Imaging: Backs up drives while they are in use without interrupting system operation.
2. Restore & Recovery
- Machine Independent Restoration (M.I.R.): Restores a system image to a computer with different hardware (e.g., new motherboard or processor).
- Selective File Restore: Mounts a backup image as a virtual drive to browse and recover individual files or folders.
- Bootable Recovery Media: Creates bootable USB, CD/DVD, or ISO media to start the system and perform a restore even when Windows fails to boot.
3. Cloning & Migration
- Disk & Partition Cloning: Creates a direct 1:1 copy of a disk or partition onto another drive.
- Physical-to-Virtual (P2V) Migration: Converts system images into virtual hard disks (VHD/VHDX) for use in virtual machines.
- Virtual-to-Physical (V2P) Support: Restores virtual machine images back to physical hardware.
4. Automation & Security
- Scheduled Backups: Automates backup tasks with flexible scheduling.
- AES Encryption: Protects backup images with 128/256-bit encryption and password protection.
