A protected machine fails to complete a snapshot. In the stack trace you see one of the next errors:
' Snapshot not created so nothing to delete Alphaleonis.Win32.Vss.VssDeleteSnapshotsFailedException: Deletion of snapshot failed. See inner exception for details. ---> Alphaleonis.Win32.Vss.VssObjectNotFoundException: The requested object does not exist. --- End of inner exception stack trace --- at Alphaleonis.Win32.Vss.VssBackupComponents.DeleteSnapshotSet(Guid snapshotSetId, Boolean forceDelete) at Replay.Agent.Implementation.ShadowCopy.ShadowCopyInstance.CleanupBackup()

Set the Microsoft Software Shadow Copy Provider Service to 'Manual'. The agent should complete a snapshot either at the next snapshot interval or forced.
If the service state is 'Stop Pending' or 'Start Pending' then kill the process and start it manually or reboot the computer and test, you should get a successful snapshot. This indicates that the service is not working correctly. Proceed to install latest updates and scan the operating system with SFC /scannow.
