Backup Philosophy: DVD's & HDD's?

[xenigo]

So here's my deal. I'm backing up some super important content I'm shooting that needs to exist no matter what. Here's the question; Should I use both DVD's and HDD's to back it up? Or should I use only HDD's. Keep in mind, there will be redundancy either way - multiple locations.

My thought is that the time involved in both burning and restoring from DVD is a pain in the fucking ass. But HDD's are both fast, and will pretty much live forever - as long as you don't keep them plugged in.
