I have just learnt of a feature in Vista that seems a fantastic idea.
It is called Shadow Copy and only available in the Business, Enterprise, and Ultimate editions. So far this is the only I see that I would want over the Premium edition I have.
What is it?
Have you ever accidentally overwritten an important document by making changes and then saving your work using the same file name? If so, you’ll appreciate the Previous Versions feature, also known as Shadow Copies. It retains earlier versions of data files and enables you to retrieve them from the file’s Properties dialog box.
