In our network we've got two servers, both AD domain controllers. Server A hosts the vast majority of the services - DNS, dhcp, exchange, etc. Server B is a DC but otherwise only a fileserver. This was done to alleviate some of the strain on server A when large files are copied (this would nearly completely lock up quickbooks for the users, the other main function of server A). My solution to this was to configure a namespace on server A that contained four folders pointing at Server B. The namespace works perfectly, haven't had any issue. The problem is I need to have the files somewhere on Server A to be backed up nightly. I have tried several replication group setups and while I can get the Topology successfully verified notice and Event Viewer shows connections no files seem to replicate. I've read that increasing the staging area folder size helps (especially since there are some huge files) but I've got it over twice the size of the largest files and still no go.
I'm also assuming the replicated folders and files will be browsable - I got it to make the root of the replicated folders on one attempt (It created a "Share" folder where there was none) but it was never populated.
The only other things I can think to mention are that the folders on Server A aren't shared (so people don't yank files off of it) and the local paths are different on each machine. Also, Server A is 2008 SBS and Server B is 2003 R2. DFS Rep and RPC are running on both properly and they can browse each other, just not replicate. Please let me know what other info I've left out!
