The size of this file is no problem. I routinely back up a VMware virtual disk
file which, currently, is about 7.3GB.

I'm not familiar with Zope, but it's safe to say that Bacula does not have the
ability to access individual files within the Zope database. The SOP with
other databases (e.g., Sqlite, Mysql, PostgreSQL, etc.) is to stop the
database, perform a dump using the database support tools, and then back up
the dump. (WRT VMware, it's possible to run an instance of a Bacula Client
within the VMware virtual machine.)

Of the top of my head I would say that you need to define two pools, one for
the daily backups & one for the weekly backups, with appropriate retention
times (two days, more or less). Whether backing up to tape or hard drive, I
would suggest storing one full backup per volume & then rotating volumes as
appropriate.
