When you guys copy the data away from Steam, and then when you want to restore it just paste it back into the steamapps, how do you get it to update the registry, etc? I did this with duels of the planeswalkers recently just messing around, and I could play the game by double clicking the .exe in the game's folder, but it didn't show up on the steam list, it didn't get into the registry, and cloud saves didn't work. Now I just do backups for single games whenever I download a game since it does save a little space but really because I'm starting to actually hit my 250 gb bandwidth cap more regularly.
