There are a number of apps out there that will tar/cpio files into proper
size (640MB/4.x GB) files that will fit into a CD/DVD.  Some create a
catalog for searching.  Most will mkisofs/burn it too.

I think there's an app out there that will let you create extra ECC for DVDs
too (dvd disaster?).

But then your files are all in a single file on a CD/DVD.

I've been looking for something similar to archive the family photos to DVDs
and still have them online.  I've decided to just create a directory for
each DVD and archive it when it gets full.  Then I create another directory.
