What is dfsr.exe?

Part of Distributed File System Replication by Microsoft

What is it?

The Distributed File System Replication (DFSR) service is a state-based, multimaster replication engine that supports replication scheduling and bandwidth throttling. DFSR uses a compression algorithm known as remote differential compression (RDC).
Description of dfsr.exe from Microsoft
You can use the DFSR WMI provider to create tools for configuring and monitoring the DFSR service. RDC is a "diff-over-the wire" client/server protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, and rearrangements of data in files, enabling DFSR to replicate only the changed file blocks when files are updated. For more information about DFSR, see Introduction to DFS Replication. DFSR is supported on Windows server operating systems beginning with Windows Server 2003 R2. It is supported on Windows Vista, but it is not supported on any other Windows client operating systems.
(dfsr.exe is a system file that is installed with Windows)
