Note
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 
therefore uses significantly more space per message than the other features. Because of this 
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. 
  •
If you enable centralized web reporting but there is no disk space allocated for reporting, then 
centralized web reporting will not work until disk space is allocated. 
  •
If you reduce the existing allocation, then the oldest data is deleted until all data fits within the new 
allocation amount. If the new quota is larger than the currently used disk space, you will not lose 
data. 
  •
If you set the allocation to zero, no data is retained.
Reallocating Disk Space Quotas 
If the appliance frequently runs out of disk space for a particular feature and has excess space for other 
features, you can reallocate disk quotas to relieve the problem. If you require more space for all features, 
consider upgrading your hardware.
