I have a Windows 7 computer that I want to re-format. This computer became increasingly used for a specific client. Because of this, a lot of customizations were added that I would not like to lose in the event the client needs me down the road. In hind-sight, I would have like to have created a Virtual PC image first. But, it just became one more thing after another over time.
Regardless, I would like to backup the whole thing (operating system, database, etc). The reason why is I may need to restore this "computer" somewhere down the road. Is it possible for me to backup the whole thing to a USB drive and somehow restore it later? If so, how?
