Sorry but to read or write dvd you need electric & mechanicals devices.
What about to write thousand dvd with a drive having a defective laser, that
could only be detected when the dvd reading
is try on another drive.

I don't speak about usb stick (really usb stick suck most of the time and have
a limited number of write )
I'm speaking about real hardrive but connected with usb2 ( hotplug, easy,
reliable ) most of time 3 to 5 years warranty
and take little place. Even more most off them could run aes256 encryption
(which is needed if exported outside)
like this one
http://www.maxtor.com/en/hard-drive-backup/external-drives/maxtor-onetouch-4-mini.html
just usb powered no external surge, doesn't take place and are very quiet with
energy efficient (sleep & wake up)
500Go is around 106 DVD : sure it would take more place than one disk :-)
(don't forget the dvd drive also ...)
But the most important is to said that external disks concept is easy to setup
with bacula.
DVD has some trouble with the lastest version ( As previously mentionned on the
thread )
After it's a choice of taste & colors :-)
Just try to use what you feel most comfortable with, or can . ( With DVD I have
to wake up 3 times by night to store the daily
backup ... And blue-ray is just too much expensive like tape. So I choose
harddrive, and yes server are not in my sleeping room
:-)))
