Please configure 'Archiving' to restrict the database growth as follows,
1. Go to Admin tab -> Archive Events
2. Enter number of days you wish to keep the data in the database for live reporting
3. Save the settings
The data older than number of days specified will be taken off of the database, compressed and moved to the destination, however you could still generate report off of the archives on demand.
