Alert!
When uploading firmware to the SonicWALL, you must not interrupt the Web browser by closing the

corrupted.

When you click Create Backup, the SonicWALL takes a “snapshot” of your current system state, firmware
and configuration preferences, and makes it the new System Backup firmware image. Clicking Create
Backup overwrites the existing System Backup firmware image as necessary.

SafeMode allows easy firmware and preferences management as well as quick recovery from uncertain

SafeMode. SafeMode allows you to select the firmware version to load and reboot the SonicWALL.
