Bacula does much more than what rsync etc do.  Bacula also updates the 
Catalog database, for example.  That is the usual bottleneck.

Note: I believe that the bandwidth you are looking at is 'data 
transfered' / 'time for job'.  The time for a job is longer than that 
taken to transfer the data.  Thus, the bandwidth used will ALWAYS be 
less than the practical maxiumu.
