Overview of System features Appliance Management Benefits of using the internal rescue image Benefits of using the internal rescue image include: • When managing your Email and Web Security Appliances, having the image for each appliance stored on a protected partition on the hard disk or USB drive for each appliance enables you to remotely reimage your appliances without needing to locate a CD containing the correct version of the software. • The rescue image negates the requirement for remote access cards to be fitted to your appliance (if you have suitable appliance models) in order for the appliances to be reimaged from a remote location. • By creating a library of stored rescue images on your local network or on a local FTP or HTTP server, you can use the rescue images to roll back your appliance to a previous .iso release of the software, or to upgrade to a newer version. You do this by importing the required image to the rescue partition on your appliance and then forcing your appliance to boot from the newly imported rescue image using the Perform a full installation overwriting existing data option. To roll back, you need to use the option 2 or 3 settings; to upgrade you need to use option 2, 3 or 4 settings.
