Verifique os logs do agente do Hyper-V vProtect e o erro será semelhante a: 
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

O tamanho padrão de WSMan:\localhost\MaxEnvelopeSizeKb é 500 (Kilobytes), que é 512.000 bytes.

Se o agente tentar transferir mais dados via DDboost do que isso, uma exceção será lançada.

Resolution

Acesse o hypervisor que hospeda a máquina virtual que tem o backup com falha.
Verifique o tamanho de WSMan:\localhost\MaxEnvelopeSizeKb (com o PowerShell como administrador) 
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>

Aumente o valor padrão de 500 para um valor maior que o número de bytes enviados 
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>

Execute o backup novamente
