DVD-RAM was built with the intention that it keeps data save for 30
years. DVD-RAM has a defect management. DVD-RAM has a metallic dye
different to DVD-R, DVD+R, DVD-RW, DVD+RW, CD-R, CD-RW. DVD-RAM is much
slower (! 3x or 5x) than the other optical formats. DVD-RAM is available in 
catridges
to protect the media against physical harm, there are even DVD-RAM
burners which accepts directly the catridge.

But it is, as any phase change media, not suited for archival long term
backup.

See: http://en.wikipedia.org/wiki/Dvd-ram

The information of the metallic dye was only on german wikipedia:
