Not an expert, but it seems like you need to determine whether the problem is with bacula, or something underlying.
Even if it's just a quick test, I would copy a large file to the destination, and time it, to figure out if the non-bacula transfer speed is consistent with the bacula backup jobs or not. If both bacula and non-bacula transfers to that destination are approximately the same speed, then it's probably something underlying. Possibly the USB bus, or the drives themselves. Possibly even the drive's underlying filesystem and FS tuning parameters (if any). If the two transfer speeds are inconsistent (most likely much faster for the non-bacula copy, than the bacula job), then I would look at bacula tuning. Like Heitor, I'd recommend looking at the database first. I know that we saw a massive speedup when I moved our bacula db tables from MyISAM tables to InnoDB tables, and massively increased how much of the table that the MySQL daemon kept in RAM. It was pretty dramatic. But then again, we have a very large database, so I'm not sure how applicable this will be for you.
