Moin,

ich habe gerade Probleme dem QEMU Client Agend die Rechte für VSS zuzuweisen:
The qemu guest agent runs default as "Network Service" Windows user and this user has default not the permission to run the vss writer. If you want the ability to run the vss and profit from consistence snapshots you have to grant this service this permission.
Wie muss ich da vorgehen?
 
Der Teil im Wiki Artikel ist leider veraltet (Werde ich nachher korrigieren). Man sollte eigentlich nichts machen müssen damit es funktioniert.
Es gibt einen QEMU GA VSS Provider Service der startet mit fsfreeze
 
Moin,
evtl. habe ich mich zu früh gefreut. Wenn ich ein Snapshot Backup starte, erhalte ich folgende Fehlermeldung im Event Log:

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.

Grüße

Gregor
