To set the automatic deletion options of the device for log storage, as shown in the following figure.

Log Preservation/Deletion: Set whether the system needs to automatically delete the access control logs recorded by selecting Auto-delete logs after xx days. You can set a duration within which logs should be preserved. By selecting Delete the earliest log if disk usage reaches xx, you can preserve logs according to the disk usage percentage.

Deleted logs cannot be retrieved. It is recommended that Syslog, Cyber Command systems, etc., be added for log backup.

Merge Logs of Same Type: After checking Enable, the built-in data center only records one activity of access to the same domain name to save the device's disk space.

Maximum Exported Entries: The number of logs allowed to be exported. Exporting too many logs will consume a large number of resources, such as memory and CPU.
