DFS Management

Applies To: Windows Storage Server 2008

The Distributed File System (DFS) solution in Windows Storage Server 2008 provides simplified, fault-tolerant access to files and WAN–friendly replication. DFS consists of two technologies:

  • DFS Namespaces

    Formerly known as DFS, DFS Namespaces allows administrators to group shared folders that are located on different servers and present them to users as a virtual tree of folders known as a namespace. A namespace provides numerous benefits, including increased availability of data, load sharing, and simplified data migration.

  • DFS Replication

    The successor to File Replication Service (FRS), DFS Replication is a state-based, multimaster replication engine that supports scheduling and bandwidth throttling. DFS Replication uses a compression algorithm known as Remote Differential Compression (RDC). RDC is a protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, re-arrangements of data in files, enabling DFS Replication to replicate only the deltas (changes) when files are updated.

    noteNote
    DFS Replication is not supported on Failover Clusters, and it is not available on Windows Storage Server 2008 Basic Edition.
