The SWARM sends the measuring data to Honeycomb every hour. So there's no need for the SWARM to save a lot of data. However, there is one exception here. If the SWARM (temporarily) loses the 3G / 4G / LTE, WiFi or PoE internet connection, and thus cannot send any data to Honeycomb, it is very important that the SWARM does save data until the data connection is restored. This can happen automatically or by the SWARM user who discovers this disconnection in Honeycomb and then fixes the connection. The measuring data is then still sent to Honeycomb after the connection is restored.
The SWARM can store 15 Mbyte of data. This equals plus minus 200,000 log records with a save level of 2s, no traces and a schedule from 9 a.m. to 5 p.m. for two weeks.
