How to Check DFS replication state

Last updated: Oct 28, 2024

Intro

OS: Windows Server

From a Windows server, it's not so easy to check the status of DFS replication. As far as I know, there is no graphical window that provides this king of information. So, after some research, I discovered that we could get information from the command line.

dfsrdiag command

Options

/SMem : The DNS name of the sender.
/RMem : The DNS name of the receiver.
/RGName : Replication group name.
/RFName : Replication folder name.

Graphical representation

To make things a little clearer, the correspondence between the dfs manager and the options:

Examples

Know the number of files to replicate from SRV01 to SRV02:

 C:\Users\Administrator> dfsrdiag backlog /SMem:SRV01 /RGName:Rep_Folder /RFName:share /RMem:SRV02

Display current updates for a specific server:

 C:\Users\Administrator> dfsrdiag replicationstate /Mem:srv01

Display current updates for all servers:

 C:\Users\Administrator> dfsrdiag replicationstate /all
