Unknown error at end of backup

I just installed and setup my first System Recovery 2013 backup job on my Windows 8 workstation.  The job says it completes successfully but in the log on the E Drive I get the following message:

Date: 7/27/2013 23:19:05 PM

Notification Type: Info

Priority: High

Description: Info 6C8F1F7E: A scheduled incremental recovery point of drive E:\ was created successfully. Unknown Error

I've mounted the volume successfully and run verify against the job and the E drive backup shows as valid.  Should I just ignore this.  I recieved it both after my first full backup and the first scheduled incremental backup.
