Optical (DVD) Backup Software

I just replaced the server on our small office peer to peer network and had a DVD-RW drive installed. I’m looking for a good backup software for our daily backups that supports optical drives. So far I’ve only found the one that NTI makes and would like to look at all my options before settling on the first I find. Anyone have any experience with daily backups with DVD-RW drives? If I can find good software, this has to be better than the tape system we’ve used for the last 4 years! BTW, I’ve email the makers of Drive Image and they replied stating that they do not support any of the DVD recorders currently on the market, only CD recorders.
