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 -> 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
