Wait for job or volume copy to appear :-)

Actually, much of the needed stuff already exists in Bacula; if you 
know what you're doing, you might be able to live with the current 
state and actually use migration as a copy of data. You'll need a 
thorough understanding of what happens in Bacula, in the catalog, and 
with the volumes, though, so this is not what I recommend to a new user.

Anyway, some more information can be found in the list archives - look 
for posts from Peter Much, named "A general concept".

If you want to used released and documented features, today you need 
to run the jobs twice, and live with possible differences between 
these jobs.
