What is the last event logged in the Realtime Statistics window (both in general view and when you select the particular VM to the left)?
Also, backup job debug log will certainly tell what is the job doing at that moment (it could be processing retention policy, for example).

Btw, do you have the transform to rollbacks option selected on this job?
