What command provides the most complete restoration of an R80 configuration?

The command that provides the most complete restoration of an R80 configuration is the upgrade_import command. This command is specifically designed to import a complete configuration from a previously exported file, typically created during a backup process. By using upgrade_import, you can restore settings for the entire security gateway, including policies, objects, licensing, and SmartConsole configurations, ensuring a comprehensive recovery of the system's state.

The context of why this is the optimal choice is rooted in the functionality of the other commands as well. For instance, cpconfig is used primarily for configuring Check Point services and interfaces, but it does not handle the restoration of the complete configuration state. The fwm dbimport command typically allows importing of the SmartDomain database and is usually used for importing specific database backups rather than a full configuration. Lastly, cpinfo -recover is a command that assists in recovering logs and providing info for troubleshooting but does not facilitate a complete configuration restoration.

Therefore, when looking for the most effective way to revert to a fully configured state, upgrade_import is the most comprehensive option available for restoring R80 configurations.
