Symptoms

NetWorker-modul til Microsoft (NMM) Sikkerhedskopiering af Hyper-v mislykkes for specifik virtuel maskine, andre sikkerhedskopier af virtuelle maskiner fungerer fint.

NSRNMMSV-loggen viser:

Date/Time PERF [1728317672]: Post-backup is completed
Date/Time Error: 
Date/Time  Failed to convert VM checkpoint of <VMNAME> to reference point.
Date/Time Error: 
Date/Time Deleting checkpoint of VM  <VMNAME>  

Når du aktiverer fejlfindingsniveau, Hyper-v shellmgmt Logfiler viser:

Datetime:Getting disk identifier for disk ~\Don't delete it\Virtual Hard Disks\System_GUID.avhdx

Datetime:In RunPowerShellScript() function, strScript Get-VHD -Path '~\Don't delete it\Virtual Hard Disks\<diskname>.vhdx' |select -Property DiskIdentifier

Datetime:Failed to get VMHardDiskDrive for the VM <VMNAME> The string is missing the terminator: '.

Cause

Under sikkerhedskopieringen vises følgende PowerShell-kommando for at hente VHDX-identifikatoren til den virtuelle maskine 

Get-VHD -Path  <VHDX_PaTH> | select -Property DiskIdentifier

Hvis navnet på den virtuelle maskine eller stinavnet indeholder ikke-understøttede tegn, mislykkes sikkerhedskopieringen.

I dette tilfælde havde stien Slet den ikke

Resolution

Skift navnet på den virtuelle maskine og/eller diskstien, undgå at bruge enkelte anførselstegn eller specialtegn
