When running a backup, you may receive the following error:
The transfer failed: 'Call to service method https://10.253.254.13:8009/apprecovery/api/agent/transfer/snapshots POST failed: The transfer failed: 'Key being added: 'Alphaleonis.Win32.Vss.VssWMComponent'''
If you found the following message when running vshadow: The writer 'MSMQ Writer (MSMQ$MSMQ-2-cpsmMsmq1)' is now entirely excluded from the backup: (it does not contain any components that can be potentially included in the backup) Discover explicitly included components ...
And also on the Agent logs the following message can be found: Alphaleonis.Win32.Vss.VssObjectNotFoundException: The requested object does not exist.
To solve this issue, exclude the MSMQ from backup. Go to Transfer settings on the Agent. Click "Change" button and exclude writer.
