In the Restore Backup section, select the subset of data to restore in the Restore area drop-down menu (or leave it set to All):
Next to Configuration file, click on the Browse button and use the dialog box to navigate to an XML backup file that you previously saved.
If the backup file is encrypted, check the Encryption checkbox and enter the password in the Password text field.
Click on the Restore Configuration button. A dialog box will appear, asking you to confirm that you want to restore the configuration. The firewall will reboot after restoration is complete.
If there are packages to restore, click on the Reinstall Packages button.
