You're correct--my bad. I chose the catalog backup as a sample job which, as 
it happens, only contains one file! After taking a quick look at the make 
tables script for my version, it doesn't appear that the size of the 
individual files backed up is stored in the catalog.

From my Bacula manual:

If you use the default bacula-dir.conf or some variation of it, you will note
that it logs all the Bacula output to a file. To avoid that this file grows
without limit, we recommend that you copy the file logrotate from the
scripts/logrotate to /etc/logrotate.d/bacula. This will cause the log
file to be rotated once a month and kept for a maximum of 5 months. You
may want to edit this file to change the default log rotation preferences.
