Thank you for your message.

To extend the retention period of the monitoring data over one year, I invite you to increase the value of Historic Sensor Data under Setup > System Administration > Core & Probes (/systemsetup.htm?tabid=4). Here is the corresponding manual: https://www.paessler.com/manuals/prtg/probes_settings#purging.

If you have questions, do not hesitate.
