The registration process is normally a manual process that should be initiated form an already installed appliance. Note that a CacheGuard appliance on a public cloud is automatically registered during its deployment. To begin the registration process it is more convenient to use the Web administration GUI as you will be asked to connect to the CacheGuard appliance registration Web portal to get an OTP (One Time Password).
To begin the registration process, go to the menu option [GENERAL] > [Main Settings] > [Registration & Subscription] of the Web administration GUI and follow given instructions. Please refer to the register command in the Commands Manual for further information.
Backup & Restore
To allow you to quickly recover a crashed machine due to a hardware or software issue, the configuration of a CacheGuard appliance and its essential data (antivirus signatures, URL lists, SSL certificates...) can be saved on a file server and then be restored on a freshly installed CacheGuard appliance (by reinstalling CacheGuard-OS on a new machine). To backup a CacheGuard appliance, you should A system first create a backup file on your appliance and then save that backup file on a trusted file server. The backup creation is a process that runs in background and you have to wait for its termination before being able to save the created backup file.
To create and save a system backup named "cacheguard.backup" on the trusted TFTP server having the IP address 172.18.2.1 use the following commands:
Patching the OS is always subject to risk. That's why it is highly recommended that you save your logical configuration and all its related data/files (SSL certificates, custom WAF rules, antivirus whitelist...) on a trusted file server before proceeding with an OS patch. In this way, you will be able to reinstall your CacheGuard appliance from scratch by installing the latest CacheGuard-OS version on it and then restore your configuration. The section Reinstalling the OS below describes how to easily recover a CacheGuard appliance configuration.
OS patches can be loaded on a CacheGuard appliance from a trusted file server and then be applied to the appliance (refer to the access file command to declare a file server as trusted). To load a patch file named CacheGuard-UF-64-2.1.3-patch.cgp from the trusted TFTP server having the IP address 172.18.2.1, use the following commands:
Caution: during the patching operation, it is highly recommended to take all precautions to avoid any power shortage on your CacheGuard appliance. If during the patching operation your machine is accidentally turned off or if, for an unforeseeable reason, the patching operation fails, the appliance may fall into an inconsistent state and then, the only recovery solution would be to reinstall CacheGuard-OS on your machine and then manually restore your configuration.
Reinstalling the OS
Some major CacheGuard-OS versions may be released without providing an OS patch. Those releases require that you reinstall CacheGuard-OS from scratch on your machine. In order to avoid having to manually reconfigure your newly installed CacheGuard appliance, you can save its logical configuration and all data/files related to that logical configuration (SSL certificates, custom WAF rules, antivirus whitelist...) on a trusted file server. In this way, you will be able to restore them on your newly installed CacheGuard appliance.
To save the logical configuration of a CacheGuard appliance in a file named "CG.conf" and all its related data in separated files in a folder named "CGFiles" located on a TFTP server having the IP address 172.18.2.1, use the following commands:
