Questi tipi di errori si spiegano da soli. Questi errori indicano che l'account utente per i servizi Avamar (agente locale e agente cluster) non dispone di autorizzazioni sufficienti per eseguire le query WMI (Strumentazione gestione Windows).

Per risolvere questo problema, concedere le autorizzazioni corrette all'account utente utilizzato per eseguire i servizi Avamar Client.

Per correggere le autorizzazioni utente di backup, consultare l'articolo della Knowledge Base riportato di seguito:
Avamar: Plug-in Hyper V: come creare e configurare manualmente l'account utente con e senza l'utilizzo dei privilegi di amministratore di dominio.

Questo aspetto è menzionato anche in modo più dettagliato nella "Dell Avamar for Hyper-V User Guide". Consultare il link alla guida per versione 19.10 o per qualsiasi altra versione consultare la pagina del supporto Avamar .
