but i get this error if i start the next job...

15-Jul 22:07 stf-bac1-dir JobId 304487:   File "/etc/bacula/scripts/DirStartUp.py", line 71, in JobInit
15-Jul 22:07 stf-bac1-dir JobId 304487:
15-Jul 22:07 stf-bac1-dir JobId 304487: AttributeError

Any pythen experts are there wich can help me to get this script working?

Thanks for help.

Hello All,

I m looking for examples about phyton startup scripts... My issue is, that i will change the priority of jobs to the starting time.

the script should look for an fullbackup-job and if this job exists and run... all other jobs should get an higher priority. If this job not running, configured priority should not changed.

Any one have an idea or implemented similar solution?

Thanks for help and

Best Regards

JHN
