Eu alcancei meu objetivo com esta diretiva Job Resource :
Job { ... RunScript { Command = "/etc/bacula/scripts/run_my_job" RunsWhen = After RunsOnFailure = yes RunsOnClient = no RunsOnSuccess = no } ... }
/etc/bacula/scripts/run_my_job
precisa ser chmod +x
/etc/bacula/scripts/run_my_job
content é:
#!/bin/sh echo "run job=my_job yes" | bconsole
