DFS replication troubleshooting
Hi,
I have a 2008 server in London and 1 in NY, they're configured for continous DFS replication. Recently we had a problem with our vpn link. I've managed to get the vpn link working, but we now have some out of sync files between US and UK. Would my best solution to sync the files be to do a manual 2 way replication ?
Throwing in some more info - the share is just under 5gb, accessed by around 9 users and the London connection speed is provided by BT at up to 20mbps. I've noticed a number of DFS errors on the London server such as "server does not recognize replication partner or group", on the NY server the DFS logs look good. I've ran some diagnostics from the NY server:
Propagation test - successful both ways
Propagation report - successful both ways
Health report - only 1 warning "pre existing content is not replicated and is consuming disk space"
What's the best way to ensure up to date files at both sites?
Would I be better off scheduling replication rather than continuous (the service is being stopped for backups)?
Could the bandwidth or amount of data be causing a problem?
Any advice much appreciated
thx

I think that you definitely not be starting/stopping the services to allow backups to take place. Use scheduling if you want to not have DFS occur during backups.
Also I think you should look into the TechNet link, see if your configuration is consistent with some of their examples. But that error you mention sounds like probably the first thing you should resolve. Does that still appear or does it go away?

whoajack,
thanks for reply, i still get the server does not recognize replication partner or group, which for over the past 7 days seems to coincide with scheduled backups.
Just to confirm, you'd recommend scheduling backups and replication times to be mutually exclusive?

I think you can actually leave DFS as-is, but you have to do one of two things (i think).
1) use a VSS type of backup, such as Windows Server Backup
2) ensure your backup software is configured to NOT update the archive bit

who, thanks for the tip, we're currently using windows server backup
will follow thru with your link, thx

Hi Dbhatoa, any updates? Hope all's well.

sorry, couldn't find an answer, nothing worked, I've simply pointed London users to the US server

Submitting this as a partial answer, as whilst I agree with the comments, it's not exactly what I was after.
will re-move DFS shares and re-create from scratch to get a healthy sync
