Back-up time?

Hey. Th9is may seem like  silly auestion but I fell like I had to ask. I'm currently tryingto back up my computer using norton 360 by burning them onto blu-ray discs. It's been and hour and ahlf or more by now that he computer has been burning the disc and I'm wondering if that's normal. Should it be really taking this long to burn one disc?
