This article lists programs that interoperate correctly with the NTFS file system and with the File Replication Service (FRS).
The FRS is a multi-threaded, multi-master replication engine that replaces the LANMan Directory Replication service (LMRepl service) on domain controllers that run Microsoft Windows NT version 3.x or 4.0. Windows 2000-based domain controllers and servers use the FRS to replicate system policy and logon scripts for Microsoft network clients. The FRS can also replicate content between Windows 2000-based and Windows Server 2003-based servers that host the same fault-tolerant Distributed File System (DFS) root or child targets.
The Update Sequence Number (USN) journal is a log of fixed size that records all changes that occur on NTFS partitions. The FRS monitors the NTFS USN journal files and uses the "file close" event to initiate the replication of files and folders in folder trees for which FRS replication has been enabled. "File close" events that can trigger replication include creating or deleting a file, a version change to an existing file, or resetting the permissions on a file or folder.
Some disk optimization programs, file-system backup programs, and antivirus programs modify files or folders, or their metadata, in the file system. These modifications may cause "closed file" events in the NTFS file system that trigger FRS replication. Because such programs frequently scan every file and folder in an FRS-replicated tree, this interaction is similar to requesting a full synchronization of all the files and folders from every server or domain controller that is running the interacting program. Administrators may see the following symptoms in their environments:
Programs that do not trigger FRS replicationThe following programs were tested and found not to modify files in a way that triggers FRS replication. However, note that this list will not be maintained. If you have questions about the compatibility of any one of the products that are listed, contact the corresponding third-party vendor.
