Unlike reporting (which is just counters) and tracking (which stores limited amounts of header
information), the spam quarantine stores the entire message bodies of quarantined messages, and

significant space usage, the spam quarantine disk quota has stricter limitations than just the available
disk space, in order to avoid locking up the appliance.

Centralized Reporting Disk Space on Security Management appliances is used for both Email and
Web data. If you enable either Centralized Email Reporting or Centralized Web Reporting, all of the
space is dedicated to the enabled feature. If you enable both, Email and Web reporting data share
the space and space is allocated on a first-come basis.
