Win32 Api Failed Exception: Failed to get the size

Backups fail with a similar error:

Volume transfer network error Network error during transfer of data from volume: Win32 Api Failed Exception: Failed to get the size of '\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37' - The device is not ready Replay.Core.Implementation.Transfer.VolumeDataReaderStream.ProcessIoRequestsWithQueueing(Int32 initialQueueSize) at Replay.Core.Implementation.Transfer.VolumeDataReaderStream.b__0() at System.Threading.Tasks.Task.Execute()<--- ---> (Inner Exception #5) Replay.Core.Contracts.Transfer.CoreVolumeTransferNetworkErrorException: Network error during transfer of data from volume ---> Replay.Common.Contracts.Win32Api.Win32ApiFailedException: Failed to get the size of '\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37' - The device is not ready at Replay.Common.Implementation.Win32Api.NativeMethods.ThrowLastError(String message, Object[] args) at Replay.Common.Implementation.Win32Api.NativeIOReader.GetFileSize() at Replay.Agent.Implementation.Transfer.TransferDataConnection.HandleReque

This error is caused by the shadow copy on the agent server being deleting prior to the AppAssure/Rapid Recovery backup completing successfully. 

To resolve this issue please increase the shadow copy storage limit for the failing volume.  The simplest method is to remove the limitation by setting it to no limit.  To do this:

1. Remote to the agent system and open My Computer
2. Right-click on the drive that is failing, choose “Configure Shadow Copies”
3. Highlight the failing drive and click the “Settings” button
4. Choose the “No limit” radio button
5. Click OK to save the setting.
6. Click OK again to close the Shadow Copies dialogue box
7. Restart the AppAssure/Rapid Recovery Agent
8. Restart Shadow Copy Services

Once the setting has been changed, force a new snapshot of the agent.
