Hi guys,
I have (2) 2008 R2 file servers. One is production and one is for DR. First, I have to make sure that the DR server never writes back to production in any situation. The means that if the (2) servers stop communicating with each other and data is deleted off the production server, the read-only DR server does not put deleted files back onto the production server when connection is restored, etc. It sounds like I am covered there.
The question is what happens if production server crashes and I now want to change the DR server to production? Does the data on the D/R member still have the same NTFS permissions? It sounds like it does, but would I then just go into dfsmgmt.msc and mark the replicated folder as read-write, force AD replication, run a dfsrdiag pollad, and then redirect the users to the DR server? I know the content may not be 100%, but the back-up plan has always been to disablestrictnamechecking, change the host record for the production server to the IP address of the DR server, and redirect users there for 99% of the data. I think that files that were open on the production server that crashed would not have had their updates replicated across. Let me know if that would work from the DFS side of things
