Description

Data Duplication System and Method for Ships The present invention relates to a system and method for duplicating data in a ship. Backup refers to copying data to another storage medium for safekeeping, while duplication refers to configuring various facilities for service provision in duplicate. Although they differ in that backup aims to preserve data so that it can be recovered in the event of loss, whereas duplication aims to provide services continuously without interruption, both backup and duplication share a similar objective in terms of disaster recovery. Redundancy methods can be broadly classified into four types as follows. 1) A method that configures a backup system identical to the main system and processes and operates data simultaneously on both systems, enabling immediate switching in the event of a disaster. 2) A method that configures a backup system nearly identical in level to the main system and processes and operates data in real-time, enabling replacement within a few hours in the event of a disaster. 3) A method that configures the basic and major facilities of the main system into a backup system and transmits data from the previous day to the backup system, enabling replacement within a few days in the event of a disaster. 4) A method in which only the basic facilities of the main system are configured as a backup system, enabling replacement within approximately one month in the event of a disaster. However, there is a problem in that even the simplest method 4) is almost impossible to implement in the limited space of a ship when applying the above redundancy method to each piece of equipment installed on the ship. Figure 1 schematically illustrates a conventional redundancy system for ships. Referring to FIG. 1, a conventional redundancy system for ships duplicates the system for major facilities specified in the International Convention for the Safety of Life at Sea (SOLAS), such as navigation, power, and propulsion, as shown in FIG. 1 (a). In the case of redundant facilities, if a failure occurs in the main system (100), it switches to the backup system (200) so that operation can continue without interruption. There are no redundancy regulations for the Voyage Data Recorder (VDR), Voyage Log, and port entry documents, but for important data that needs to be prepared for a disaster, the data is backed up in storage (300) as shown in Fig. 1 (b). According to conventional redundancy systems for ships, there was a problem in that only redundancy for some equipment and backup for some data were provided, making it impossible to prepare for disasters affecting other equipment and data. Figure 1 schematically illustrates a conventional redundancy system for ships. FIG. 2 schematically illustrates the ship data redundancy system of the present invention. FIG. 3 schematically illustrates the ship data redundancy method of the present invention. Figure 4 schematically illustrates a system for managing data backed up to storage in the present invention. Figure 5 schematically illustrates a method for managing data backed up to storage in the present invention. The configuration and operation of a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. The present invention can be applied in various fields, such as the marine industry, backup and redundancy fields, etc. Furthermore, the following embodiments may be modified in various different forms, and the scope of the present invention is not limited to the following embodiments. Figure 2 schematically illustrates the ship data redundancy system of the present invention. Referring to FIG. 2, the data redundancy system for ships according to the present invention redundantly configures the main system (100) and the backup system (200) for each ship equipment (400). While one backup system (200) may be configured for each ship equipment (400), the system may also be redundantly configured by configuring one or more backup systems (200). The data redundancy system for a ship according to the present invention stores data of the main system (100) (hereinafter referred to as "main data") by configuring a data storage area (150) for the main system separated from the main system (100), and stores data of the backup system (200) (hereinafter referred to as "backup data") by configuring a data storage area (250) for the backup system separated from the backup system (200). When the backup system (200) is configured in multiple units, the data storage area (250) for the backup system may also be configured in multiple units corresponding to each backup system (200). The data storage area (150) for the main system may be separated from the main system (100) by a partition or configured as a separate storage medium. Likewise, the data storage area (250) for the backup system may be separated from the backup system (200) by a partition or configured as a separate storage medium. T
