Norton Online Backup Maintenance Message

Yesterday I installed Norton Online Backup 2.0 through a download from Norton. Last evening I began the initial backup and it was at about 8% when I went to bed. This morning I simply keep getting a message that "NOBU is Busy Doing Maintenance" though I see no announcement of this on any site. 

 

Is this correct, or is this really an error message of some sort?

 

I'm running Vista as an OS.
