Unlike Apple's iOS devices, Apple TV has no backup system, yet. The latest iTunes only shows two options when an Apple TV is connected. They are, Restore (as new) and Eject. Until backup is added and supported by Apple, there is no way to restore your previous settings, apps and data back to an Apple TV. Instead. settings must re-entered anew. Apps must must re-downloaded. Home screen icons must be moved around again. Even then, the previous configuration and progress on most apps will be lost. Being able to backup is important. I suspect a future update will add this “feature” soon. But in the mean time...be careful.
