Kontroller loggene for Hyper-V vProtect-agenten, og feilen ligner på: 
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), som er 512 000 byte.

Hvis agenten prøver å overføre mer data over DDboost enn dette, oppstår et unntak.

Resolution

Få tilgang til hypervisoren som er vert for den virtuelle maskinen som har den mislykkede sikkerhetskopien.
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>

Øke verdien fra standardverdien på 500 til en verdi som er større enn antall byte som 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
