Unless there is an error in the documentation I have done as recommended in this section. Prefer Mounted Volumes is not set in my configuration so the default should be used which is "yes". My jobs are started at 5 min interval so bacula *really should* use the same drive and volume for each job (as it does for the first job). I can not see any reason why it behaves differently for Job 2.
