Tung,
ADAudit Plus helps us maintaining historical data over years with effective disk management through archiving. We can find the option under 'Admin' tab -> Archive events. The feature allows us to archive processed data from the database that are older than what is required for immediate reporting from live database. Data older than number of days we specified in the settings, would be taken off of the database, compressed and stored in the archive folder which can be restored on demand.
Regards,
ADAudit Plus Team
