I would not assume that DVD backups will have a long life-time. I
have not seen any field tests of lifetime for DVDs, but for CD-Rom
some of the real-world testing showed they were only reliable for a
year or so.
If you do any research on this, be sure to differenciate between
Manufactured DVDs and ones made in a typical DVD writer. That was the
big difference for CDs. Manufactured (or pressed) CDs do last a long
time, it is the burned ones that don't.
As far as I know, good tape media is still the preferred archival
storage medium, and even it is only rated for 20 years. I guess you
know a good tape drive is still pretty expensive.

Has anybody used a DVD burner to make archival copies of images on a
linux-based forensic computer?
What I imagine doing is dumping an image to a DVD(s) after an analysis
is over so that the image can be archived for an indefinite period of
time. I'd think I could use something like "dd
if=/images/TestCase_hda1.img | dvdrecord -dev=0,0,0 -data -". Obviously
that doesn't work or I wouldn't be asking the question.
Once I get that working, then I'm gonna want to be able to burn larger
images to multiple dvds using some combination of the skip and count
switches...but one thing at a time;)
