I think it would help knowing the bacula version you are running and 
your gluster setup.

Bacula v7 has a "Maximum Bandwidth" for the job definition and "Maximum 
Bandwidth Per Job" for the FileDaemon definition as described in [1].

Regarding the gluster part if you can use the fuse gluster client ( it 
has better performance, balancing reads and writes between gluster 
nodes  and provides high availability ) in the machine where you are 
mounting the USB drive and limit the bandwidth with the parameters 
described in the bacula documentation link.

Or, if you are not using bacula yet, and all you want to do is to copy 
the data this one time, mount the gluster volume as before and use rsync 
with --bwlimit=<KBs>
