I can't find any reference to 'Job Policy' in the Bacula documentation.

What do you mean by that?

Retention refers to meta data.  Specifically, what Files were backed up 
on
what Clients, by what Jobs, and to what Volumes.  Retention does not 
refer
to how long backups are kept, but they are related.  See later.  This 
meta-data
is retained in the Catalog (the database).

There are three retention values: File, Job, Volume.

To make it easiest when restoring a job, I always keep all three values 
equal to
each other.  Some people prefer to minimize their Catalog size.  I 
emphasize ease
of restore over database size.  Disk space is cheap compared to the 
time spent
when you need to restore data.

If your File retention period has lapsed, you will no longer be able to 
restore individual files.

If your Job retention period has lapsed, you will no longer be able to 
restore individual job.

Does that help?

I would start a new thread, with that as the subject. It is best not to
ask multiple topics in one email.  :)
