FRS Overview

File Replication Service (FRS) is a multimaster replication service used to replicate files and folders in SYSVOL file shares and in DFS link targets. FRS works by detecting changes to file and folders in a replica set, and then replicating those changes to other replica members, which are connected in a replication topology. Because FRS is a multimaster replication service, any member of a replica set can generate changes, and FRS can resolve file and folder conflicts to make data consistent among the replica members.
