Are you reporting a real problem that you have seen in operation, or are you 
just imagining there might be a problem?  

If it is the former, please explain what it breaking.  If it is the latter, 
you should bring this up first on the bacula-users list so they can fill you 
in on all the details.

In the output below, you don't show two important things: 1. the InChanger 
flag (as mentioned by Frank),  and 2. the StorageId.

Best regards,

Kern
