Sets the lifespan (in days) of the logged data in the database. If value is 0, then data is always available, otherwise the database can destroy data after the number of specified days.
The database only discards data if new data is logged. This property affects all data from the library stored in the database, not just the most recent data. For example, if you set this property to four days and you have three days of data, the database does not destroy any data. However, if you set this same property to two days from four days and you have three days of data, the database can destroy any data collected more than two days ago.{| class="wikitable"
