Dell local backup message to create restore disc

Hi everyone.

Hope this is the right place for this question...

I'm wondering if anyone knows if it's really necessary to create the restoration discs since I have got both the operating system and the drivers on separate DVDs when I purchased the computer. I keep getting a message from Dell Local backup to create these but I've been too chicken to tell it to stop bugging me but at the same time I don't want to have any more DVDs lying around than necessary.

Any input would be appreciated.

Cheers.
