image creation, no changes should be made to the configuration. Upon completion, the appliance
will reboot. The backup image will reside inside the appliance but must be downloaded before it can
be used. See Booting from the Network on page 124 for Netboot restoration steps.

2. Click Create Backup Image and click OK.
NOTE: The appliance can only store one image at a time.
