Animation overwrite

I’m not sure exactly what forum area this question should be in, if this is the wrong place I apologize. So, I’m relatively new to the Animation feature in Unity and have been making great use of it lately. I have a scene that has been laid out exactly how I want it (Terrain design, object placements, etc.) and I am animating a story which will be broken into 3 scenes. For the first part, I have spent weeks getting the movement/animation of the Main Camera just right, and today began working on the 2nd scene. To do this I created a prefab which holds all of the objects from scene 1, created scene 2 and dragged this prefab into the scene. I then proceeded to spend all day getting the animation for this scene correct. Now, while scene 2 is exactly how I want it, when I go back to scene 1, the animation for Main Camera pulls the animation for scene 2, so something has obviously been overwritten. Luckily I have a backup of everything from a few weeks ago, so I completely removed Main Camera.controller and Main Camera.controller.meta and replaced them with my backup copy; however, it still shows the animation I created today. Is there any way to get my original animation back? Any help will be GREATLY appreciated. Thank you.

Sorry all, I figured it out. I realized I was replacing the controller when I should have been replacing the anim files.
