Wow, you seem to have a lot of spare time. How long does it take you to perform all these checks? I do backups to usb hard drives. They have 40GB to 120GB and it takes on the order of 1 minute / GB to diff -r them. Considering lifetime and how often you're able to rewrite / reuse the media, they are cheaper per GB than CDs/DVDs. I guess I will realize soon enough, whenever usb and/or ext3 will be phased out and replaced by a different technology and will then move the data to new media / formats.
