If you are working with a firewall already existing in your configuration, you should make a system backup prior to configuring the firewall to work with Cloud Secure Edge. The backup is a snapshot of your current system state, SonicOS image, and configuration preferences. The snapshot becomes the new system backup image.
To make a firewall backup
For more information about backups on the firewall, refer to SonicOS 7.1 Device Settings Administration Guide or the SonicOS 8 Device Settings Administration Guide, as needed.
