The configuration section contains some tools to keep track of your setup.
Backup
You can backup and restore your machines configuration using the System › Configuration › Backups section. When performing a local backup, you can choose to protect it with a password and decide whether or not you would like to store rrd statistics as well (in which case they will be stored in the same export xml file).
Restoring backups can either be performed partially or for the complete configuration. Since configurations usually have various components that depend on each other, it’s most safe to restore a complete configuration.
Defaults
With the defaults tool you can reset your firewall back to firmware defaults and shutdown when done.
History
The history menu helps you track changes between modifications and offer the opportunity to download older versions of your settings.
Each backup preserved on this machine will be presented as an item in the dropdown, when selecting an item, the previous backup (when available) will be selected automatically as comparison target.
