  • I can't seem to find any information on DFS-R as it relates to moving around directories within the share.  When this is done, does DFS just updates the new patching structure to its partners, or does it delete and create all those "new" files, thus generating a lot more WAN traffic ?

  • For DFS-R this is effectively the same as a rename operation - the hash of the files contained in the folders aren't changing so they don't need to be replicated again.
