ODIN

ODIN (Open Disk Imager in a Nutshell): Führt ein Backup ausgewählter lokaler Festplatten durch und erstellt dazu ein Image des Datenträgers, das sich jederzeit wiederherstellen lässt; sichert auf Wunsch auch nur die genutzten Cluster einer Platte, sodass es kein Image der gesamten Festplatte schreiben muss; ab Version 0.2 unterstützt es Disk Snapshots.

ODIN is a utility for easy backup of hard drive volumes or complete hard drives under Windows. A disk image can be created or restored. Only used clusters can be backuped, compression on the fly is possible.

It runs under 32-Bit Windows Operating Systems. 

How many hours did you spend in setting up your Windows system? Setting up the operating system, installing programs, customizing to your personal needs. Do you want to be protected against hard disk failures, viruses or other malware? Just restore your system within minutes. Why spend money for a commercial solution? ODIN supports snapshots can be run from command line or with a GUI and runs on 32-Bit and 46-Bit operating systems.
