#!/bin/bash
#
# Um Script para Bacula Restore Test

# Seleciona, aleatoriamente, x (files_per_job) para restaurar de cada Bacula Configured Client para um Restore Client fixo.
#
# Sugestão e local:

    fi
done

Don’t forget to provide execution permission to the script. E.g.:

chmod o+rx /etc/bacula/scripts/restore_test.sh

Create an Admin Job at bacula-dir.conf in order to execute the script when desired. E.g.:

Job {
  Name = "RestoreTestJobsCreator"
  JobDefs = "DefaultJob"
  Type = Admin
  Client=hfaria-K46CB-fd
  Messages = Standard
  Schedule = "test_schedule"
  RunBeforeJob = /etc/bacula/scripts/restore_test.sh
}

Create the dedicated Schedule to run the tests series (e.g.: every wonderful Monday):

Schedule {
  Name = "test_schedule"
  Run = Full  monday at 12:00
}

Check the Restore Job logs for eventual errors and also the health of the restored files at the Restore Client machine.
