Kontroller Hyper-V vProtect-agentlogfilerne, og fejlen vil ligne: 

2024/04/10 20:27:06.761 [e4b640a5-7784-4195-a909-6294d3763d0f] Microsoft.Management.Infrastructure.CimException: The WS-Management service cannot process the request. The computed response packet size (585610) exceeds the maximum envelope size that is allowed (512000).
   at Microsoft.Management.Infrastructure.Internal.Operations.CimSyncEnumeratorBase`1.MoveNext()
   at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source)
   at Microsoft.Management.Infrastructure.CimSession.InvokeMethod(String namespaceName, CimInstance instance, String methodName, CimMethodParametersCollection methodParameters, CimOperationOptions options)

Cause

Standardstørrelsen på WSMan:\localhost\MaxEnvelopeSizeKb er 500 (kilobyte), hvilket er 512.000 bytes.

Hvis agenten forsøger at overføre flere data DDboost End dette kastes en undtagelse.

Resolution

Få adgang til hypervisoren, der er vært for den virtuelle maskine, som har den fejlbehæftede sikkerhedskopiering.
Kontroller størrelsen på WSMan:\localhost\MaxEnvelopeSizeKb (med PowerShell som administrator)

PS C:\Users\Administrator> Get-Item -Path WSMan:\localhost\MaxEnvelopeSizeKb


   WSManConfig: Microsoft.WSMan.Management\WSMan::localhost

Type            Name                           SourceOfValue   Value
----            ----                           -------------   -----
System.String   MaxEnvelopeSizekb                              500


PS C:\Users\Administrator>


Forøg værdien fra standardværdien 500 til en værdi, der er større end antallet af byte, der sendes 

PS C:\Users\Administrator> Set-Item -Path WSMan:\localhost\MaxEnvelopeSizeKb 600
PS C:\Users\Administrator> Get-Item -Path WSMan:\localhost\MaxEnvelopeSizeKb


   WSManConfig: Microsoft.WSMan.Management\WSMan::localhost

Type            Name                           SourceOfValue   Value
----            ----                           -------------   -----
System.String   MaxEnvelopeSizekb                              600
