Cloud tiering is the feature of Azure File Sync that actively helps reduce the physical storage used on local servers. This mechanism allows frequently accessed files to remain locally stored while less frequently accessed files are moved to Azure, effectively creating a hybrid storage environment.

By utilizing cloud tiering, local servers can maintain efficiency and performance as they only keep the most relevant data on-premises. When files are not needed immediately, they can reside in the cloud, thereby minimizing the on-site storage requirements and optimizing resource allocation. This approach not only enhances local storage capacity but also leverages the scalability and reliability of Azure's cloud services.

The other options, while significant in their own right, do not directly contribute to reducing physical storage on local servers. For instance, geo-replication focuses on ensuring data availability across multiple geographical regions, access control pertains to user permissions and security without affecting storage size, and snapshot management deals with data recovery and protection. Therefore, cloud tiering is distinctly responsible for the efficient use of local storage resources in the context of Azure File Sync.
