Since circa 1982, I have tried dozens of back up utilities and
utilities that claim they will let you burn files/backup to DVDs (or
other media) from collections of files.

The typical problems they have are:

1. bugs (Nero)

2. cannot work unattended. You must prod them along every step of the
way.

3. They want you to specify the files with a GUI. I want to run this
unattended.

4. The list of files to backup is not smart enough to deal with new
files or deleted files if you reuse the list.

5. They are dead slow. I would like to produce a disc-at-once.

6. proprietary formats that put the restore process in danger.

I have already written a front end to a backup utility that maintains
a zipped mirror of the files you want to back up called BackupToZip.

Perhaps I could finish it off with Java code to do the burn. I did
not see anything in a cursory google search. My own entry was at the
top of the list -- not much help. Has anyone ever heard of a Java
library for burning DVDs?

Failing that a script/file driven utility available for a suitable
number of Java platforms that could be exec ed to do the work.

First: burning DVD's seems to be the mid-00's way - you should look
at an online solution today - and Java is perfect for that.

If you insist on using DVD's then I can see 3 roads forward
with Java:
A) find an open source burner software and call it via JNI
B) find something that exposes a writable DVD as a writeable
    disk to the OS so you can move files onto it with standard
    Java IO
C) let Java copy the files to a staging area and use a native
    tool to burn from that area
