Does Norton Resume Backing Up if Computer Reboots?

I've been using Norton backup (NOBU) since it took over @Backup in March, 2013.  Recently, I totally revamped how it backed up because I saw that backing up by file extensions wasn't removing files on their server that I'd removed from my computer.  So, I'm now in the middle of a day's long process of it backing up a fresh copy by file folders.  It will be 8,334 files and 22GB when it finishes.

It's been about 30 hours and I'm at 37% transferred.  If my computer reboots, will I lose this, or will Norton resume where it left off?
