What Gets Saved in a .prefab BackupUnity 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 PropertiesThese will be backed up in every prefab version:Transform (position, rotation, scale)MeshRenderer, MeshFilter, SkinnedMeshRendererMaterials, TexturesBoxCollider, SphereCollider, CapsuleCollider, MeshCollider (all their settings: size, isTrigger, center, etc.)Rigidbody (mass, drag, interpolation, collision detection, constraints)Script components with [SerializeField] or public fieldsAnimator (controller, avatar, apply root motion, etc.)AudioSourceNavMeshAgent, Light, Camera etc.Basically, if it's a component visible in the Inspector, and the fields are serializable, they're savedWhat Doesn’t Get SavedSome 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)SupportHave questions or need help?Contact us at support@thegamergage.com — we're happy to help!FeaturesSave unlimited prefab versions with timestamped backupsOne-click restore to any previous versionOrganized version folder per prefabDelete old versions with easeAuto-creates backup folder if missingNon-destructive workflow – original prefab is preservedBuilt-in Unity Editor window UIWorks seamlessly with nested prefabsSimple and clean codebase for easy extensionSupported OSWindowsmacOSLinux (Editor only)Requires Unity Editor (no runtime dependency).

I designed the tool logic, UI layout, and user experience on my own, and only used AI for syntax suggestions and help with debugging. All the final code was manually tested, customized, and optimized for production use. The asset includes significant custom logic, editor GUI design, and modular architecture. No part of the asset was copy-pasted without human review or editing.
