 What Gets Saved in a .prefab Backup

Unity prefab files preserve all serialized properties, which means that virtually everything visible in the Inspector for components gets saved. Here's a breakdown:

 Commonly Saved Properties

These will be backed up in every prefab version:

• Transform (position, rotation, scale)
• MeshRenderer, MeshFilter, SkinnedMeshRenderer
• Materials, Textures
• BoxCollider, SphereCollider, CapsuleCollider, MeshCollider (all their settings: size, isTrigger, center, etc.)
• Rigidbody (mass, drag, interpolation, collision detection, constraints)
• Script components with [SerializeField] or public fields
• Animator (controller, avatar, apply root motion, etc.)
• AudioSource
• NavMeshAgent, Light, Camera etc.

Basically, if it's a component visible in the Inspector, and the fields are serializable, they're saved

What Doesn’t Get Saved

Some things are not stored in the .prefab file directly:

• Editor-only components/scripts (e.g., [ExecuteInEditMode] with non-serialized fields)
• Runtime-only data (anything modified only in Start() or Update() and not serialized)
• Missing script references (won’t recover if the script is deleted from project)
