Roll Back the Virtual Appliance to a Previous Time Point
- You can restore the virtual appliance to a previous state in case of system crashes or configuration errors.

Ensure that the Backup tab is open. The list of available backup archives is displayed with their details and control buttons under Backup sets. If the USB drive containing backup archives is plugged-in to the virtual appliance, the backups stored in it are also displayed.
- Click the 'Restore' button in the row of the required backup archive. A Confirmation dialog will appear.
- Click 'OK' in the confirmation dialog.
- The restore operation will replace the current firewall configuration with that of the backup.
