ProSecure Unified Threat Management (UTM) Appliance
Log Management
Generated logs take up space and resources on the UTM internal disk. To ensure that there
is always sufficient space to save newer logs, the UTM automatically deletes older logs
whenever the total log size reaches 50 percent of the allocated file size for each log type.
Automated log purging means that you do not need to manage the size of the UTM logs
constantly and ensures that the latest malware threats and traffic activities are always
recorded.
Note: After the UTM reboots, traffic logs are lost. Therefore, NETGEAR
recommends that you connect the UTM to a syslog server to save
the traffic logs externally. Other logs (that is, nontraffic logs) are
automatically backed up on the UTM every 15 minutes. However, if
a power failure affects the UTM, logs that were created within this
15-minute period are lost.
For information about how to purge selected logs manually, see Configure and Activate
System, Email, and Syslog Logs on page 467.

3. You have selected to quarantine emails, attachments, objects, and web files on one or
more of the following screens:
