How long will WeatherLink.com keep my weather data (historical information)? If my data account is full, does it stop adding data or write over the oldest data?

WeatherLink.com emulates the behavior of your console (or Envoy). It stores four times the amount of data on your console/Envoy. Depending on the archive interval, up to 800 days (just over 2 years) worth of weather data will be stored on WeatherLink.com. If you wish to keep your weather data for a longer duration, we suggest you periodically download your weather data from WeatherLink.com to your own PC using the WeatherLink software.
