In a cloud storage system, you need to implement file versioning to track changes made by different users. How would you approach this using file system techniques?

Implementing file versioning in a cloud storage system can be achieved through various techniques. Using metadata attributes within the file system to track version history, timestamps, and user identifiers helps maintain a history of modifications. This approach is more efficient than creating copies of entire files or using delta encoding, as it provides a clear record of changes while minimizing storage overhead. Snapshot technology and version control systems are also effective but may involve additional complexities compared to metadata-based version tracking within the file system.
