I started from copying the Windows files to another partition with Explorer. It worked, but restoring of such a copy was not an easy task. After many experiments I've noticed it is possible to restore just 8:3 file names from the Windows folder, then to run the system with such a partial copy, then to restore files with long names from WINSTART.BAT script. And this idea and ARJ compression utility becomed the foundation of my backup application.
The final version makes snapshots of Windows and Program Files folders excluding temp and Temporary Internet Files folders. This covers the system registry and all config data. With such a copy it is possible to restore the system to a new disk drive in case of a critical HDD failure, or to replace the current damaged or infected system with the previously made copy.
The whole solution was targeted towards my clients needs. If the system became problematic it is possible to restore it from the CONFIG.SYS menu. That way I do not have to go to my clients office by myself, because the client can restore the system by himself in most cases, sometimes with a minor telephone help or suggestion.
I found it takes much less time to restore the whole system, than to clean it with AV software. The system copies can be stored on the same partition as the Windows is located. It is possible to restore from a bootable CD drive, as well.
The application was made in the Polish language only, I'm afraid.
