SQL Server database maintenance
Every morning at 5 am the ARM server completes scheduled maintenance by removing and archiving old scans from the ARM data base. These settings can be managed in the menu item server in the storage of scans section.
Scheduled data base maintenance is only performed if all ARM user interfaces are closed. You can identify logged in users in the menu item server status.
