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. The System Backup
shows you the current configuration and firmware in a single,
clickable restore image.
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.
