DFS Replication efficiency for WIM files

A customer asked us how efficiently DFS Replication replicates changes made to Microsoft Windows Imaging Format (WIM) image files. (WIM images are created by ImageX, the disk imaging tool in Windows Vista.) It just so happens we tested this recently with two consecutive Windows Vista builds, and the results were impressive: a 91.59% reduction (151.59 MB replicated instead of 1.76 GB). And if you’re running Windows Server 2003 R2, Enterprise Edition on the sending or receiving server, you don’t need to worry about keeping the same name for each version of the WIM image thanks to cross-file RDC.
