Cause

Dit soort fouten spreekt voor zich. Deze fouten betekenen dat het gebruikersaccount voor de Avamar-services (lokale agent en clusteragent) niet voldoende machtigingen heeft om de Windows Management Instrumentation (WMI)-query's uit te voeren.

 

U kunt dit probleem verhelpen door de juiste machtigingen te verlenen aan het gebruikersaccount dat wordt gebruikt om de Avamar clientservices uit te voeren.

 

Resolution

Volg het onderstaande KB-artikel om de machtigingen van de back-upgebruiker te corrigeren:
Avamar: Hyper V plug-in - Het gebruikersaccount handmatig maken en configureren met en zonder het gebruik van domeinbeheerdersrechten.

 

Additional Information

Dit wordt ook in meer detail vermeld in de "Gebruikershandleiding van Dell Avamar voor Hyper-V". Zie de koppeling naar de handleiding voor versie 19.10 of zie voor een andere versie de Avamar support-pagina.
