Re: [Bacula-users] How to prevent to schedule a job if the same job is still running
Hi Stephen, Perhaps it's possible with this configuration: >>> Allow Higher Duplicates = no >>> Cancel Running Duplicates = yes You can also try to change the Schedule to avoid incremental backups starting when full backups are running. It costs a more complicated schedule resource but it's much better tested/documented. Cheers, Bram.

[Bacula-users] example python script: limiting number of concurrent full backups
Hi All,
We wanted to limit the number of concurrent full backups. It's not
possible to configure it in the configuration file without affecting the
number of concurrent incremental backups. I created a small Python
script to downgrade Full backups to Incremental if more than 2 Full
backups are running.
Not much python scripting examples exist so I attached our script. Feel
free to comment or use it as a starting point for your own scripts.
Cheers,
Bram.

If you have a job that takes more than 24h to complete a runs daily, it will never finish. Hope it helps. When I find some try I will reopen the bug report.

If you have multiple jobs running simultaneously, one job can spool data while the other is despooling.

[Bacula-users] duplicate job control
Dear All,
Bacula (3.0.2) is configured to make daily backups of some systems. Full
backups unfortunately take more then one day to complete and I want to
avoid that duplicate jobs start (or are queued) before the full backup
is completed.
No duplicate job control directives are configured. If I understand the
manual correctly (perhaps it's an interpretation error of me)
http://www.bacula.org/en/dev-manual/New_Features.html#SECTION00310
this should not happen.
I had a quick look in the source code and found this code in src/dird/job.c:
bool allow_duplicate_job(JCR *jcr)
{
JOB *job = jcr->job;
JCR *djcr;/* possible duplicate */
if (job->AllowDuplicateJobs) {
return true;
}
if (!job->AllowHigherDuplicates) {
--> code related to "Cancel Queued Duplicates: and "Cancel Running
Duplicates" here
}
return true;
}
Apparently "Cancel Queued Duplicates" and "Cancel Running Duplicates"
are only evaluated when "Allow Higher Duplicates" is set to "no" - not
default. Is this an error in the documentation, code or me not correctly
understanding the manual or code?
Kind regards,
Bram Vandoren.

[Bacula-users] Total Automation of Bacula Tape Handling
Hi, We are using Bacula in our organisation. (Single tapedrive/no autochanger) I am currently changing the tapes myself but want to give other (non IT) persons also the possibility to do this job. When they receive an email they should insert a new tape and bacula has to continue with the job. It should be fool proof (eg when someone inserts a wrong tape it should unmount the tape and send an email again). This should be possible with the script described in the documentation: http://www.bacula.org/rel-manual/Tips_Suggestions.html#SECTION003816 Unfortunately the script seems not be updated for a long time and doesn't want to play nicely with our tape drive. Should I try fixing the script (i already found some of the problems in it) or is there a better solution? I thought about writing a script (executed by cron every x minutes) that checks if it should do something depending of the output of "status storage" and the "messages" output. Any ideas ?
