Abstract: With the exponential rise in cloud storage usage and the growing demand for cross-platform accessibility, efficient file synchronization has become a critical requirement in modern computing environments. Traditional synchronization techniques, which often rely on full-file transfers and timestamp-based comparisons, are no longer sufficient—particularly in bandwidth-constrained or resource-limited scenarios such as mobile networks and edge computing systems. This paper presents a hybrid synchronization approach that integrates Two-Way Synchronization and Differential Synchronization to improve efficiency, reduce bandwidth consumption, and enhance data consistency. Two-Way Synchronization enables the detection and resolution of file changes from both local and cloud sources, supporting intelligent decision-making for conflict resolution, deletion propagation, and duplicate handling. Differential Synchronization enhances this process by transmitting only the modified segments of files, using techniques such as block-level comparison and rolling hashes, thereby significantly minimizing data transfer volume and synchronization time. The paper outlines the architecture, entities, processes, and data flows involved in each technique, along with corresponding algorithms and flowcharts. Finally, the paper identifies future challenges, focusing on component-level implementation, delta generation, metadata management, and cloud integration. The proposed solution offers a scalable and bandwidth-efficient synchronization framework suitable for real-time collaboration, offline-to-online transitions, and deployment in distributed and hybrid cloud environments.
