For now I'm going to assume I want to return 0, quick-fix this

Yeah, returning 0 is the hack I did to the dvd-handler script.
Excellent, I did something right. :) Thanks for confirming.
Gah.
Now I can mount it but not label it!

Hmm. Are you sure the DVD you're trying to label was a blank disk?
Brand new disc fresh out of the case. All I've done so far is attempt
to label it, and manually format it using dvd+rw-format. I suppose one
of my attempts to label it might have written something to it, but so
far the error messages I've gotten suggest to me that it hasn't gotten
that far. ("Sorry, I have to mount it before I can label it, and I
can't mount it.") In fact, I had the storage device definition wrong at
first, so it would have been impossible to label it then. Once I got my
definitions correct I started getting the error above; so a non-blank
medium represents a cart-before-the-horse problem. :)
The trick that worked for me is to _not_ attempt to label disks
manually; rather, use automatic labeling - using that strategy, I can
write backups to DVD, even spanning more than one disk.
(The problem seems to be that, even if labeling worked, Bacula would not
currently overwrite an existing volume - which would be necessary to
convert the PRE_LABEL created by labeling to the normal start-of-volume
label.)
Also, you might want to check and make sure that the dir you
specified as Spool Directory is empty; your previous attempts at
labeling might have left stray files there that confused things this
time.
Same issue; previous attempts were with the wrong definition, so it
didn't have a directory to work with. Nonetheless I'll check both
possibilities out next chance I get (probably tonight or tomorrow
after I get home, I'm visiting the parents right now).
Other than that, I'm out of ideas.
Yeah. And the reply I got earlier suggesting that it's no better under
Linux and DVD writing isn't ready yet doesn't make me feel much better.
Well, if you're interested I can not only confirm that DVD writing is
possible, but I could even supply a working setup. That is, a setup that
has worked but is untested since I'm currently busy beta-testing newer
versions of Bacula.
Using one of the development version 1.37, I even tailored a working
backup solution to DVD for a customer. Which was, by the way, seriously
limited - no automatic volume recycling, and each disk had to be
prepared by a script I supplied. Apart from the hassle actually using
that this setup did work and probably still does. The customer, though,
decided to migrate to disk based backups for now and I'm currently
defining what sort of tape based solution would best suit their needs.
(That's the common problem with older DDS and DVD backups - the constant
need of intervention. A fully automatic tape based solution is usually
the best way, IMO).
I was really hoping to migrate away from these DDS-3 tapes. I seem to
have avoided the reliability problems many people claim, but by today's
standards they're slow and expensive. And these are wearing out. DVD is
a medium that's cheap, both drives and media, due to economies of
scale. Hard drives are now cheap enough to be a serious contender, but
I was really hoping to keep my budget down even lower. There's still
something like a 2x (+RW) to 5x (+R) gap from what I've seen.
Today I will not write down my experiences and the reports I know off
concerning reliability of DVD media :-)
