Before beginning the update process, make a system backup on your SonicWall NSv. When you click the Create Backup button, SonicOS takes a “snapshot” of your current system state, SonicOS image, and configuration preferences, and makes the snapshot the new System Backup image. You can save Backups locally or on the cloud. You can also schedule backups to occur automatically. Clicking Create Backup overwrites the existing Backup image as necessary.
You can also export the NSv configuration settings to a file on your local management station. This file serves as an external backup of the configuration settings, and can be imported into another NSv or into the same NSv if it is necessary to reboot SonicOS with factory default settings.

Local Backup – SonicOS takes a “snapshot” of your current system state, firmware, and configuration preferences, and saves it as the latest local backup file.
In the Local Backup dialog, optionally select Retain Local Backup to prevent this backup from being overwritten by a future local backup. Optionally enter a comment in the Comment field, and then click OK to proceed with the backup.
