Hi !
Firstoff: My company is still willing to support a developer that
implements data migration into bacula.
I have a few questions considering tape handling.
Let`s say i have a Tape that gets changed every day. Three servers
backup to it (spooling of course) and i have set Maximum Volume Jobs to
3 for that pool.
I'd suggest to not use the Maximum Volume Jobs but rather setting the
Volume Use Duration.
Is there a way to automatically eject the tape after the last server
finished spooling his data ? Maybe with the Run After Job directive ? I
could do it by hand with the console but thats not what i want.
You could do this with a Run After Job Script that feeds the necessary
commands to bconsole and uses mt rewoffl to eject the tape from the
drive. That should be the easiest soluion for now.
For the future, with python scripts and event methods called from
bacula, I'd do it differently: Nag Kern to implement a "volume status
change" event, and use that to unload the drive. This would be foolproof
in case your job order gets mixed up.
What happens if one backup fails and i remove the tape so that maximum
volume jobs is not fulfilled ... will it ask for the old tape on the
next backup or will it happily use the new tape that has been inserted ?
Depending on the setting of "Use Any Volume" it might ask for the old
tape, but would also use the new one.
The relabel command only works on tapes already in the catalogue ... i
re-initialized my database a few times and it rejected relabeling the
old tapes. It also rejected USING the old tapes ... had to do "mt weof"
to fix that.
There's the add command - although that doesn't add the tapes contents
to the catalog. You can use bscan for that purpose.
Do i need to set the Drive Index option in bacula-sd.conf when i don`t
have a tapechanger ? I only have 4 standalone LTO-1 drives but no changer.
No, you shouldn't set that, but it won't hurt because that information
is only used to control an autochanger.
Best regards
Arno
