Distributed File System (DFS) allows administrators to group shared folders located on different servers and present them to users as a virtual tree of folders known as a namespace. A namespace has many benefits, including increased availability of data, load sharing, and simplified data migration. DFS Replication allows administrators to replicate folders in a bandwidth-efficient manner using the remote differential compression (RDC) algorithm that replicates only the changed blocks within a file.
DFS Namespaces and DFS Replication are useful for the following purposes:
Organizing a large number of file shares scattered across multiple servers into a contiguous namespace so that users can find the files they need
