The Backup & Restore configuration section allows us to save the system settings as an XML file. With this XML file, we can restore pfSense to these settings in two different ways:
- After a hardware or software failure, we can reinstall pfSense, and then restore the previous configuration using the previously-saved back up XML file.
- In the absence of a hardware or software failure; say, we just want to rollback pfSense to a previous restore point, then we can use the previously-saved back up file to do so.
