Because the automatic backup configuration file, AUTOLOAD.NAS, is automatically updated by the caching system each time any configuration change is applied (see The AUTOLOAD.NAS File), we recommend saving your appliance configuration to a .NAS file with another name.
If you ever need to reimage your appliance for some reason, having an alternatively named .NAS file will provide a configuration backup in case the AUTOLOAD.NAS file is overwritten with factory settings before your configuration is restored.
If you want to automatically load a configuration using the settings in an alternatively named file, you can use a workstation and replace the system-created AUTOLOAD.NAS file with a copy of your file on the floppy disk before inserting it into the appliance's floppy disk drive.
