I love this product, more than once, backup on my WHS saved me. WHS system backup is also very good to rollback my system. I created a manual backup after fresh install for all of my machines, and after my machines are fully configured.
A friend of mine was moving, and he did not have a laptop. I loaned him my laptop, gave him the laptop in a clean state after restoring the laptop from the fully-configured backup. After he returned the laptop to me, I restored the laptop from the backup that I made before I gave him the laptop. He could install all the applications that he wanted, and it won’t matter to me. 🙂
