Switched today from 360 to Security - where is backup?

I paid 100 bucks today for 2 years of the new Norton Security.  They kindly credited my account 75 bucks because it had just renewed Norton 360.  If you have 360, you have to actually purchase Security.  They don't just upgrade you.  So I did all that and am running Security.  I love it.  Works great so far.  But where is my Backup?  I back up to a 4TB external drive twice a day and it is gone.  I see no backup app.  Surely since Security is an upgrade from 360 and basically replaces it, it has Backup.  Should just use Windows backup now?  What about my 3 TB of data that Norton 360 backed up using Norton Backup? I must be missing something simple here.  Certainly Norton did not abandon their backup software. It is very good.  I like it better than the free stuff that comes with WD or Seagate hard drives or any of the others...  Where is Norton Backup in Norton Security?  Thanks.
