You should be talking to your NAS people to ask them what kind of realtime data syncing capability they have within the hardware itself. We do this with our mainframe data, it is hot synced between two datacenters and it is completely managed by the underlying hardware at the block level. It is expensive but I can't think of any software that could really keep up with what you are doing.

Well, to give a little more info, we have 1,000,000+ files on our NAS. This machine is accessed pretty hard by ~1,000 users, housing .pst files and eudora data store files. If you are saying that each time there is a change in a file, it is replicated, would it constantly replicate email data files each time an email comes to the user? That could get ugly.

We looked at a DFS / FRS combo and quickly rejected it based on the problems with FRS.  For data replication, FRS is a PoS (to be brutally honest).  MS needs to start from scrtach on that one.  Any efficient data replication scheme would utilize a block level or some other low level replication process and not be based on file level replication.  A single change to, say a 10 MB file, should not trigger the replication of the entire 10 MB file.

 

We're looking at several third party replication tools but the jury is still out on the optimal solution.

Yes,

You need to become familiar with the FRS registry settings and the staging directory. Try these links to get you started:

Also,

definitely consider moving your staging directory to a large volume follow the instructions in KB291823.

We are thinking of using DFS in order to add redundancy to our NAS offerings. My main question is does anyone have experience using DFS to replicate/keep in sync large amounts of info, i.e. 200+GB, between two or more servers?

As always, thank you for the help.
