Hi Community,

 

during a backup of a Windows Server 2008 R2, the system logs several error massages with error code 8194, source VSS. I've no idea whats going wrong. Anybody out there who had the same problem and a solution for this?

 

Protokollname: Application
Quelle:    VSS
Datum:   15.09.2010 22:09:31
Ereignis-ID:  8194
Aufgabenkategorie:Keine
Ebene:   Fehler
Schlüsselwörter: Klassisch
Benutzer:   Nicht zutreffend
Computer:   ENTERPRISE-2.KASTNER.local
Beschreibung:
Volumeschattenkopie-Dienstfehler: Beim Abfragen nach der Schnittstelle "IVssWriterCallback" ist ein unerwarteter Fehler aufgetreten. hr = 0x80070005, Zugriff verweigert
. Die Ursache hierfür ist oft eine falsche Sicherheitseinstellung im Schreib- oder Anfrageprozess.

 

Thx & Bye Tom

Hi Tom,

 

I'm not sure I'm getting the same exact error as you since I can't read German but I do get the following event logged to the application log on all my Windows 2008/Windows 2008 R2 systems when retrospect backs them up, this happens at multiple sites:

Date: 9/17/2010 11:41:13 PM

Level: Error

Keywords: Classic

Computer: GAD

Description:

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.

. This is often caused by incorrect security settings in either the writer or requestor process.

I've been seeing RS backup 2x 3GB files from the System Volume Information directory (or at least I think it was that) every night.

 

From checking the logs these files compress by 99%.. but obviously take a while to copy over.

 

I have no idea what they are and why RS suddenly started backing them up! It's a hidden directory in C:\ which I can't even see from showing hidden directories.

 

Does RS even support 2008 R2 yet?
