Symptoms

NetWorker VMware Protection-integrationen (NVP) er konfigureret med vProxy-enheden.  Microsoft VM App Agent (MSVMAPPAGENT) til SQL Server-programkonsistent beskyttelse bruges til at udføre en sikkerhedskopiering af en virtuel maskine (VM) med Microsoft SQL Server.  Sikkerhedskopieringen af VM mislykkedes, hvilket indikerer, at MSSQL-agenten ikke kunne oprette en sikkerhedskopi af transaktionslogfilen.  Oplysninger om NetWorker Management Console-sessionen (NMC) og sessionslog viser:
YYYY/MM/DD HH:MM:SS INFO:   [89] MSSQL: Executed MSSQL Agent operation 'backup_transaction_log' on guest VM.
YYYY/MM/DD HH:MM:SS INFO:   [89] MSSQL: Executed MSSQL Agent operation 'monitor' on guest VM.

Cause

"NT AUTHORITY\SYSTEM" er ikke tildelt sysadmin-rettigheder til Microsoft SQL Server-databaserne.

Resolution

MSVMAPPAGENT kører under SYSTEM-kontoen for databeskyttelseshandlinger.  Konfigurer alle SQL Server-forekomster i VM for at tildele "NT AUTHORITY\SYSTEM"-konto-sysadmin-rettigheder:
