Creating a restore point may come in handy sometimes yes. I believe windows makes a default restore point when you install new updates or particular software with the windows installer and also on a regular interval base. Keep in mind this feature only applies to the system, its files and settings etc. It won't restore data that has been lost. For that you still need to make an oldfashioned data backup.

I assume you are talking about an 1 TB internal drive. Why don't you make multiple partitions? One for your OS and one (or more) for data (music, video, documents, blabla). So that way if you screw up one partition the other(s) stay intact. Unless of course the drive itself dies on you. Furthermore you could make regular automatic updates.
