19.3 Configuration File Backup and Restoration

Use the Maintenance > Configuration menus to create a file of your NSA configurations such as passwords, shares and volumes created, network settings and so on. If you’re going to do some major configuration changes, then it is advisable to create a configuration backup file. If things go wrong after you make the configuration changes, you can always go back to the previous configuration by restoring an earlier configuration file.
