B2D Backups on Backup Exec 2010 R3 Running Slow

I have Backup Exec 2010 R3, running RAWS.  I am backing up Windows 2008 R2 VM's and one Windows Exchange 2010 VM.  The backups started to run very slow this week, by that I mean they are running under 100mb per minute.  This makes them not finish on time.  I have another backup system that has the same setup.  It is not having any issues.  I have verified the jobs are the same and went menu by menu.  I have noticed that this appears to be a somewhat widespread problem.  I was hoping that someone out there had a solution.  Thank you very much.
