DFS replication in Windows 2003 R1

Hi,

Is it possible to Replicate data in Windows 2003 R1 (ie, the old version of DFS)?

When I say replication, I mean mirror the data between 2 servers. I have setup a "root" and a link between 2 servers, I'd like the actual data to be replicated between the 2 servers.

I've seen many guides online regarding dfs replication on Windows 2003 R2, I can't seem to find anything relating to the original version of DFS.

thanks,

Yes you can use DFS Namespace of Windos 2k3 R2.

DFS Namespaces. Technology that helps administrators group shared folders located on different servers and present them to users as a virtual tree of folders known as a namespace. DFS Namespaces was formerly known as Distributed File System in Windows 2000 Server and Windows Server 2003.

You can do it but it's not very reliable and the it can take some time to replicate the data.

Create the root, then your two servers under that as root targets and setup the replication.

Yes, replication is available in the pre-R2 version of DFS. The structure of the DFS objects is like this:

Root
   |---------  Link1
   |                |----------- Target 1
   |                |----------- Target 2
   |
   |---------  Link2
                    |----------- Target 1
                    |----------- Target 2
                    |----------- Target 3

The Link name defines a kind of Virtual share name within the DFS name space. Applications can connect to the Link much as if they were connecting to a shared folder. However, DFS provides the actual files from one of the targets below the link. If all the targets are available it will try to use as its source whichever is closest ("close" as defined in Windows AD Sites & Services). If a target is off-line then the alternative will be used seamlessly.

When you create a new Link, it asks you to specify the first target, but it doesn't mention replication. However, if you add a second Target to an existing Link then you get a tick box "Add this target to the replication set". Tick that box and you'll get prompted to configure replication - this opens the "Configure Replication Wizard" where you can specify replication topology etc. Take care - I have known it to replicate the empty folder to the full folder before now which is kind of embarrassing on a live system!

I've made some notes on DFS for my own benefit. They are all pre-R2. Here is a link:

Hi,

I have created Root, with 1 link and inside the link I have 2 targets, one for each server. When I created the second target it didn't give the option Add this target to the replication set (it was greyed out).

DFS namespace is available, but that isn't the same as DFS Replication, which is only available in Windows 2003 R2 and later. Windows 2003 only has the File Replication Service, which is not reliable and is not a good alternative to DFS-R.
