Abstract: The present invention discloses a backup method and backup device. The backup method for the TCP connection provided by embodiments of the present invention includes: processing a first input packet, and generating, according to a processing result of the first input packet, a new transmission control protocol status and a new socket status; backing up the generated transmission control protocol status and the generated socket status to a transmission control module of the standby board; sending a second input packet to an application module; receiving a first output packet; processing the first output packet, and generating, according to a processing result of first output packet, a new transmission control protocol status and a new socket status; and backing up the transmission control protocol status and the socket status. The present invention further discloses a backup device for a TCP connection.
