Which command provides the most complete restoration of a R80 configuration?

The command that provides the most complete restoration of a R80 configuration is the "upgrade_import" command. This command is specifically designed to import configuration files that were exported from previous versions of the Check Point management software, including full configurations with policy rules, objects, and settings.

Using "upgrade_import," you can restore a management server's entire state, making it an essential tool for administrators looking to maintain or recover comprehensive configurations after an upgrade or migration. This command ensures that all aspects of the configuration are accurately reinstated, minimizing the risk of any loss of critical settings or policies.

Other options serve different purposes. For instance, the "cpconfig" command is primarily used for configuring the Check Point system settings but does not handle complete configuration restoration. The "fwm dbimport" command, while it can import specific database objects, may not capture all custom settings and configurations in the way "upgrade_import" does. Lastly, "cpinfo -recover" deals with diagnostic information and troubleshooting rather than restoring configuration settings fully.

Thus, for a thorough restoration of a R80 configuration, "upgrade_import" stands out as the most effective choice.
