This should take care of your backup ;-)

Certance is now owned by Quantum, but I know a lot about Certance.

Seriously, current optical technology is unlikely to ever reach the
capacities of magnetic. DVD's are optical, Hard disc is magnetic.

As to RAID, it's not a backup. It can save you from a restore if a drive
fails, RAID 1 or RAID 5, not RAID 0.

Brian's recommendation of backing up to a hard disc that's kept off-line
without any power connected is the best bet for most of us.
