Those were the questions you should rather have asked yourself in order
to figure out what exactly is so special about DVD media, which makes
you wonder this questions. My standpoint is that 1/2 of solution lies in
posed question and "good backup program for DVD" is just too fuzzy.
E.g.:
> We used self written scripts which in turn used dump for ext2 to tapes.
You can use DVD as tape. Trouble is that if your average dataset is less
than single media capacity, then special care has to be taken, as you
probably don't want to waste one disc per set... Or you probably don't
want to use it as tape and pack data? You might want to keep files
accessible as single files for convenient restore...

... or maybe you on the contrary *want* to pack the data, so that it can
be *compressed* prior recording. Then "big" in combination with "full"
sounds like requirement for multi-volume. There was a post on the list
how to burn arbitrary input stream to multiple volumes...
Once again. Those are the question you should ask *yourself*. It's not
my intention to find a solution that suits some particular need, but
rather to make you and/or public to pose more "tangible" questions.

Note to the public. Things discussed off-list tend to so to say
disappear in vain. Open up and *share* your experience with public. Note
to request originator. Consider posting summary. A.
