I've been having problems with DFS the last few months. This is the last topic for background:
The servers are running Server 2008r2.
In short, replication wasn't working. Didn't know why but got it fixed. However, I noticed the last issue occurred at the same time a restore job was run on Symantec Backup Exec. I suspected that another restore job would cause the issue again.
These are two file servers (A and B) in different sites which are set up to replicate different groups. Only one of these groups is being backup'd up with Symantec Backup Exec. The problematic one.
So today I decided to test what I suspected was causing the issue.
The DFSR has been working fine for the last two weeks. No restores have been made during that time either.
I deleted one of my own folders on the drive and attempted a restore.
The restore failed per Symantec though it did recover all but one file. The last file was unimportant and I could recover it with VSS so not a big deal.
However, there were several Event ID 1112 errors (around 20) logged in DFSR Event Viewer. (DFSR failed a restore request)
5 minutes after those errors finished, a 4110 warning is logged. (DFSR has started processing a database recovery)
6 minutes after this, a 4102 error is generated. (DFSR service has initialized the replication folder)
These all occurred on the Server A, none of these errors are on Server B so of course this was caused by Symantec.
Fortunately, I'm familiar with this issue now so I set up Server A as primary and now the initialization is processing without a problem.
My question is:
What has been set up incorrectly on either DFSR or Symantec Backup Exec?
Something wrong is causing a restore with Symantec to corrupt the database and trigger it to re-initialize.
The 1112 event has this text:
"This could happen if an attempt was made to restore the contents of a read-only replicated folder authoritatively. Read-only replicated folders should only be restored non-authoritatively. Authoritative restores should be performed only on read-write replicated folders."
Is this a permissions issue?
