Pierott,
From the sound of it, you are protecting your SharePoint farm correctly. Are you able to create subsequent recovery points? I would assume from the way that you have listed the question that
configuresharepoint.exe was run on
blw301.
If this is the case, there is no need to backup the blw302 server. the Windows SharePoint Services Writer know where the various parts of the farm are located and reports that back to DPM so it knows what to backup. Simple as
that!
For more information on the specifics of how Volume Shadow Copy Services backs up SharePoint check out:
SharePoint Foundation VSS Writer
