Backing up System Reserved (SYSVOL) partition failed


#1

I am trying to complete a full image backup for a client machine and i have been unable to do so with this 1 particular machine. There were instances where the backup would begin and get to 4% before just freezing and sitting there until i stopped and restart the Urbackup service. I have uninstalled the Urbackup client from the user’s machine and reinstalled the new version v2.0.30 and I have run the batch files on the server to clean up and repair the database. Now when i go to run the full image backup the backup begins and gets to about 5% of the SYSVOL and then all of sudden errors out with the below error. I have run a defrag on the users machine before reinstalling the Urbackup client but still no fix. Any ideas?

What are your logs server-side?

Assuming you’re on a Windows Server: C:\Program Files\UrBackupServer\urbackup.log – I highly recommend you view this with Notepad++ or something equivalent that way it is actually legible.

This is what the server side debug looks like after trying to run the full image backup 3 times. The machine name is KWWARRSPEC.

I got about one guess:[quote=“uroni, post:11, topic:2189, full:true”]
ttrammell sent me some more info and the issue is probably caused by 8.3 names (DOS names). One course of action would be to mangle all 8.3 names on the server, the other to advise people to turn off 8.3 name generation.

Let’s go with the second first: See here for how to do this: https://support.microsoft.com/en-us/kb/121007 . It has performance benefits as well.

I’ll add that link to the manual as setup step. The problematic pair of file names also should be rare such that it is improbable that many other people have this kind of problem, if they have not turned off 8.3 names.

Not sure if that is right in the slightest, but it’s the only guess I got.
