A colleague of mine taught me something new about the RDC (Remote Differential Compression) cross-file feature DFS-R technology in Windows Server. Cross-file is not available in all version of windows server.
Cross-File RDC is available in:
- Windows Server 2003 R2 Enterprise Edition
- Windows Server 2008 Enterprise Edition
- Windows Server 2008 R2 Enterprise Edition
- Windows Server 2008 R2 Datacenter Edition
Cross-File RDC is not available in:
- Windows Server 2008 R2 Standard Edition
- Windows Server 2008 Standard Edition
- Windows Server 2003 R2 Standard Edition
- Windows Server 2008 Datacenter Edition
- Windows Server 2003 R2 Datacenter Edition
DFS Cross-File is a part of the RDC technology in DFS-R technology. What Cross-File does is instead of replicating the entire file, DFS Replication can use portions from files that are similar to the replicating file to minimize the amount of data transferred over the WAN. If you are planning to use this, ensure to use Enterprise Edition of windows server!
This information about what flavours of windows server cross file is available under is documented here:

Strictly speaking, Cross-File RDP operates if at least one endpoint is running Enterprise Edition. It is not required on both.
ReplyDeleteRDC even.
ReplyDeleteTo clarify here, what Anonymous is saying is the server being replicated to needs to be enterprise for Cross-File RDC compression to work. For data replicating the other way there will be no Cross-File RDC. If you want replication both ways to be compressed with Cross-File, you need Enterprise Edition on both ends.
ReplyDeleteWith Server 2012, this feature is now available in Standard Edition.
