Norton Security Suite - backup not completed

For some reason every single time I boot my system says backup[ not completed.  Even right after I manually run backup.

 

I even did a custom backup to only backup my libraries folders for a quick backup.  still get the backup not completed message.

 

Any ideas what is happening?

 

It does this on both my computers.

ps. I use the free norton's provided by comcast.

 

pss I forgot to mention I have it set for monthly backups on the 1st.  And only 1 backup set.
