OSTA ( http://www.osta.org ) still says CDRs are good for somewhere
in the 50 to 200 year range (if you stay away from the problem labels,
take care of the disks, etc.).

And put that second copy in a safe-deposit box.  Having two copies
doesn't do any good if they're sitting on the same shelf and the
house burns down or is blown away by a tornado.
