Re: [Bacula-devel] bls and DVD (Windows Version)
thanks for the response. It was not my intention to use DVDs as a
general backup media, so I agree in principal with your statements about
Normally I wrote my backup and archives on LTO Tapes but in the case
of archiving data I don't like the idea to insert tapes with already
archived data again for additional writing. On the other hand normal
archive chunks are much smaller than the capacity of a LTO tape. So the
"one tape one archive" concept is from my point of view not the best. My
idea was it to use DVD for smaller archive jobs. The biggest problem
seams to be my problem of "sharing data" with other partners because it
is not likely that all partners have Bacula running (I am sure it will
be more because I like the idea behind Bacula ;-) ). And in most cases
our partners without Bacula use Windows and not *nix.
So my idea was it to write data to one or more DVDs, send this to a
partner (without a running Bacula) and the partner can restore the data
with bls and co. on every supported platform. Maybe this is scenario is
out of scope but I like this idea. Anyway I think your workaround with
the files could work for us, thanks

I see you are probably the reporter of the bug on this same subject.
I regret, but currently we only support the FD on Win32. It turns out that
the Dir and the SD appear to work reasonably well. However, I think it is
*very* unlikely that anything using DVD on Windows will work because as far
as I know the tools that Bacula uses to read/write the DVD have not been
ported to Win32, so you are pretty much out of luck.
In any case, I would strongly recommend against using DVD as it is a very
If you must use it, then I suggest writing to disk volumes and limiting their
size to fit on a DVD, and when the Volume is full, "manually" write it to a
DVD, and if you later want to restore from it, then copy it back onto the
disk. It is not a very automatic way of working, but it is the best we can
offer at the moment.
As you will learn in the next few days, we have created a company that will
provide professional support and development services to Bacula users, so I
hope that in the future through corporate development projects, we will be
able to fund a Windows developer to fix some of the missing functionality on

My goal is it to share archive DVDs . Unfortunately I was not

Does the windows version of bls the reading of "Linux" DVDs ? Are there
any experiences with bls on Windows and DVDs ?
Command line: bls.exe -V "DVD-2008-1" "DVD Writer"
