I suggest a slightly different approach, but I don't know if it meets 
your needs.

Use the two external HDD as mirrors of the internal drives.  Let Bacula 
use only the internal drives.  With this approach:

- you always have the latest and greatest backups online and directly 
available
- you have a copy of those backups offline
- Bacula doesn't need to know anything about the offline backups

You will only ever *need* the offline backups (i.e. the external HDD) if 
the internal HDD fail.  In which case, you COPY from from the external 
HDD to the internal HDD and off you go.

How does that sound?
