Controleer de logboeken van de Hyper-V vProtect-agent en de fout is vergelijkbaar met: 

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

De standaardgrootte van WSMan:\localhost\MaxEnvelopeSizeKb is 500 (kilobytes), wat 512.000 bytes is.

Als de agent probeert meer data over te dragen via DDboost dan dit, wordt er een uitzondering gegooid.

Resolution

Krijg toegang tot de hypervisor die als host fungeert voor de virtuele machine met de mislukte back-up.
Controleer de grootte van WSMan:\localhost\MaxEnvelopeSizeKb (met PowerShell als beheerder)

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>


Verhoog de waarde van de standaardwaarde 500 naar een waarde die groter is dan het aantal bytes dat wordt verzonden 

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


PS C:\Users\Administrator>
