Hyper-V vProtect 에이전트 로그를 확인하면 다음과 유사한 오류가 나타납니다. 
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

WSMan:\localhost\MaxEnvelopeSizeMb의 기본 크기는 500(킬로바이트), 즉 512,000바이트입니다.

에이전트가 DDboost를 통해 이보다 많은 데이터를 전송하려고 하면 예외가 발생합니다.

Resolution

실패한 백업이 있는 가상 머신을 호스팅하는 하이퍼바이저에 액세스합니다.
WSMan:\localhost\MaxEnvelopeSizeKb의 크기 확인(PowerShell을 관리자로 사용) 
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>

값을 기본값인 500에서 전송되는 바이트 수보다 큰 값으로 늘립니다 
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>
