About 200 MB of storage is allocated for saving reports on the firewall. You can’t configure this limit but you can
Configure the Report Expiration Period: the firewall will automatically delete reports that exceed the period. Keep in mind that when the firewall reaches its storage limit, it automatically deletes older reports to create space even if you don’t set an expiration period. Another way to conserve system resources on the firewall is to
Disable Predefined Reports. For long-term retention of reports, you can export the reports (as described below) or
Schedule Reports for Email Delivery.
