Saving a Backup Copy of Your Preferences
Before beginning the update process, make a system backup of your SonicWALL security appliance configuration settings. The backup feature saves a copy of the current configuration settings on your SonicWALL security appliance, protecting all your existing settings in the event that it becomes necessary to return to a previous configuration state.
In addition to using the backup feature to save your current configuration state to the SonicWALL security appliance, you can export the configuration preferences file to a directory on your local management station. This file serves as an external backup of the configuration preferences, and can be imported back into the SonicWALL security appliance.
Perform the following procedures to save a backup of your configuration settings and export them to a file on your local management station:
1.On the System > Settings page, click Create Backup. Your configuration preferences are saved. The System Backup entry is displayed in the Firmware Management table.
2.To export your settings to a local file, click Export Settings. A popup window displays the name of the saved file.
