DFS Implementation

Okay, I want to set up a domain dfs root with replication for three shared folders on my network.  I have two NAS servers where I plan to host the three shared folders.  I plan on restoring from tape the three folders to each of the NAS servers, so they each have identical copies of the three shared folders.  Now, do I have to set up the domain DFS root on a DC?  The two NAS servers are domain member servers only.  Do the folder names have to be different, or because they're on different servers, can the folder names remain identical on each server, which means the dfs links will have the same name, but different paths?  These three folders, let's call them A, B, and C, have a cumulative sum of 236 GB.  Is this going to be a problem for replication and synchronization?

if you want them kept in sync by DFS (frs) it may not function as estimated.
FRS has a recommended limit of 64G of data. If you want to sync more data, ROBOCOPY is recommended.
you should not activate frs for this dfs.
just create the DFS as you sayed. create all shares, sync them and built the Domain DFS-Root.

How about, does a "domain" dfs root need to be on a DC?  And what the hell is sayed?

no, a domain DFS Root does not need to be on a DC.

Create a DFS like:

DFS-Root
             --> Target_A
                                -> \\Server1\A
                                -> \\Server2\A
             --> Target_B
                                -> \\Server1\B
                                -> \\Server2\B_with_other_name
             --> Target_C
                                -> \\Server1\C
                                -> \\Server2\C

you can use different folder names, as the Target in the DFS can have a different name as the share.

I was wrong, you did not say it.
But do it like this: Setup the Shares on each Server, sync them, built your DFS.

When you say "sync them," do you mean with ROBOCOPY?
0
WeHeCommented:
yes.
use robocopy with "/MIR" switch.

From then on can I use FRS, or do I continue to use ROBOCOPY for file replication, real time?  What I mean by real time is, as users make changes to files, are they going to be automatically replicated and synchronized in both places?

no, frs limits are allways active.

I see.  So, does ROBOCOPY accomplish the task, real time?
