DVD-RAM was cheaper (both drive and media) back before DVD-RW and DVD+RW
caught on. But that hasn't been the case since about 18-24 months ago
when DVD-RW and DVD+RW media dropped under $5. Even if DVD-RAM was even
more popular, the media cost would never be as low, large because of its
design.
DVD-R(G) compatibility is ultimate and longevity is extremely good in
Disc-at-Once (DaO) mode. So if cost is a concern, then you want to use
DVD-R(G) with GPL cdrecord+DVDpatch (or free-for-non-commercial cdrecord
+ProDVD if that doesn't work) for your backups.
In general, avoid DVD-RW, DVD+RW and DVD+R for backups if you are
worried about longevity. Especially DVD-RW and DVD+RW (which _are_ MO-
based, despite marketing to the contrary) because of the error rates of
MO. DVD-RAM mitigates this with a write-after-verify.
