Storage

Version management of object access is typically performed by tracking and controlling changes to objects (such as files, documents, or data records) over time. This ensures that previous versions can be retrieved, compared, or restored if needed.  

### Key Concepts:  
1. **Versioning**: Each modification to an object creates a new version, while retaining older versions for reference.  
2. **Access Control**: Permissions determine who can view, edit, or delete specific versions.  
3. **Audit Trails**: Logs record changes, including who made them and when.  

### Example:  
In a cloud storage system, when a user uploads a new version of a file, the system automatically creates a new version while keeping the old one. Users can revert to a previous version if necessary.  

For cloud-based solutions, **Tencent Cloud Object Storage (COS)** supports versioning, allowing users to manage multiple versions of objects within a bucket. Access control is enforced via **CAM (Cloud Access Management)** policies, ensuring only authorized users can modify or access specific versions. Additionally, **COS** provides logging features to track version changes and access activities.
