Hi Kern,
I already read dev manual, and it's extremely outdated.
Yes, I agreed.
I cloned bacula git repo two weeks ago and had been studying the code
since then.
Last week I accomplish to compile bacuka trunk (Branch-5.1) with
sucess and finish my sandbox dev environment.
Great. Branch-5.1 is definitely the right one to be working on.
This week I'm recruiting fellows from my local community and some of
my students to start a code team for this feature and possibly others.
Nice. That is a good way to get something really going ...
When I have the first usable patch it will be posted here. Until
there, any minor progress will be discussed here. I'll use all your
suggestions and guidelines for this features, and you all will be
informed of any decisions to make.
OK, thanks.
Best regards,
Kern
Best regards,

Hello Allan,
Nice.
Here are a few suggestions:
1. Read the Developer's manual, especially the programming style
guidelines.
2. Fill out an FLA (www.bacula.org <http://www.bacula.org> -> FLA
License
3. There are many additional details that need to be resolved, but
can only
be identified and resolved during the development process. For
this reason,
it is important if you want your patch to be accepted to work
fairly closely
with us, either asking us when there are important decisions to be
made
or to send us patches (or post your git repo on git hub where we
can access it).
I hope this helps,
Best regards,
Kern

Hello Kern,
I'm very interest to implement this, as I told before, this is
essential for the backup plans that I'm implementing. I'm not so
sure that I'll be capable to finish thou.
My next steps will be:
1. Contact my local "open source community" to see if I have
others volunteers.
2. Make the initial code using the design you proposed.
3. Send to this list the patch for comments.
Any additional suggestions are welcome.
Thanks.

Hello,
I have long ago worked out the basic design of Job migration
between different SDs,
but I haven't written it down, because no one has volunteered
to do the project, so
I have been planning to do it myself (if I have to do it, it
will be as a Bacula Enterprise
feature obviously). The design is basically:
1. Ensure Dir understands that two SDs are involved (possible
need for
additional directives).
2. Dir initiates connection with each of the SD's, one of
which is the
Reading SD (rSD) and one of which is the Writing SD (wSD).
3. Dir transmits the coordinates of the wSD to the rSD as
well as the necessary security token.
4. The rSD connects to the wSD as if it were a FD and uses
the FD protocol (or possibly a simplified version) to transmit
the data from the rSD to the wSD. Note, the wSD doesn't
need to know that the rSD is an SD -- it can simply think
it is an FD.
The rest of the backup proceeds as a normal back.
Is there someone who is interested to implement the project?
Best regards,
Kern

Hello,
My thoughts about it below:
2011/8/25 Allan Garcia <allan.gar...@gmail.com
<mailto:allan.gar...@gmail.com>>
(...)
MY INITIAL BRAINSTORM
1. the dird have to contact the origin *sd* and command
the migration (like it's done now)
2. the origin *sd* detects if the destination *sd* it's
himself or the other *sd*
I think Director should communicate origin SD that
destination is remote device on the other SD and supply
required connection info.
3. if the origin *sd* detects other destination, it
respond informing that to the dird
4. the dird have to handle the origin *sd* response
informing the destination *sd*
If you change #2, that above steps won't be required.
5. the dird commands the destination *sd* to wait the
origin *sd* connection
6. the dird commands waits the destination *sd* to confirm
7. the dird commands origin *sd* to send data to
destination *sd*
8. when it's done the job are marked as sucess,
otherwise fail.
Waiting for any comments...
You have to design a protocol used for SD to SD
communication including TLS/SSL encryption layer.
Best regards
