In the event of a disaster, it is essential to establish a disaster recovery plan and disaster recovery system to minimize disruption to major IT infrastructure and provide continuous business services. In the process of building a disaster recovery system, data replication is a key element of data recovery to provide uninterrupted and continuous business services in the event of a disaster. The data replication method can be determined depending on the system configuration environment and disaster recovery goal level. In this paper, we present a method for determining a data replication method suitable for the configuration environment and disaster recovery target level when building a disaster recovery system. In addition, the replication method decision procedure is applied to build a disaster recovery system and analyze the construction results. After establishing the disaster recovery system, a test was conducted to determine whether the service was transferred to the disaster recovery center in a disaster situation and normal service was provided, and the results were analyzed. As a result, it was possible to systematically select the optimal data replication method during the disaster recovery system construction phase. The established disaster recovery system has an RTO of 3.7 hours for service conversion to the disaster recovery center to provide continuous business services, and the disaster recovery level, which was Tier 2, has been improved to the target level within 4 hours of RTO and RPO=0.

The two major trends that have emerged in recent years in relation to disaster recovery and recovery are 'regional infrastructure', 'regional leadership' and 'community recovery'. In the former case, it is to avoid disaster recovery and recovery by using external personnel and resources, and to maximize the resources in the area under the initiative of the residents of the affected area. And through this process, it is to prepare a new growth engine for disaster-affected areas. In addition, the latter expands disaster recovery targets to the general population living in affected areas and is not limited to victims. Through this, we can expect to recover the 'community' beyond the individual's recovery. In the Ansan of Gyeonggi-do, where many families of 'Sewolho' live, and in the Heunghae-eup of Pohang, Gyeongbuk-do, where the damage was severe, projects are underway to restore communities. And In these areas local activists and civic groups are actively utilized to efforts are being made to increase efficiency. Nevertheless, in the case of the community recovery program being promoted in Korea, there are limitations that it can be promoted only on the basis of special laws and that participation of various actors is necessary. This study intends to propose the limitations of current projects and ways to solve them by analyzing domestic and foreign cases related to the community recovery program for disaster-affected communities using local resources. we suggest two way. One is the relaxation of the national dependence of the community recovery program, and the other is to expand the area of disaster relief through.

In the event of a disaster, we need people who specialize in rapid regional disaster recovery. However, in the present disaster response system, disaster relief is carried out at the level of public support, volunteer service, etc. There are various problems such as initial response due to lack of expertise, delays in disaster recovery, and inadequate response to disasters. Therefore, it is necessary to establish a unit with early ability to respond to local governments in the event of a disaster and expertise to enable rapid disaster recovery. Therefore, this study limited the preparation of the reserve forces emergency response units for the direction of local security, disaster relief and disaster relief through emergency disaster recovery under the disaster situation.

This study aims for improving the system in Disaster Management of Local Government. In addition, the overall disaster management system was compared to the effectiveness of the disaster prevention system and reliability, and problems and improvement points were derived. The disaster management system in Korea has a structure that promptly investigates and restores damage by a simple procedure. Korea disaster management system manages information on top-down structural disasters through the flow of prevention, preparation, response, and recovery. The process from disaster response to recovery under the leadership of the central disaster safety headquarters is simplified. Disaster management tasks are dispersed among departments, making it difficult to respond promptly. Under the control of the central government, disaster management, such as disaster prevention, investigation, and recovery, are carried out. The disaster management improvement direction of the local government should establish the disaster response system focusing on the local government. Therefore, it is necessary to have budget to operate the organization - centered disaster management budget and the disaster management organization. The disaster response manual should be prepared considering the disaster environment and disaster prevention plan. In order to utilize disaster information, it is necessary to reorganize information system such as integrate and streamline of the private resource database and NDMS.

Since most of companies these days are utilizing the Information system actively, Information System is the most important factor which should be recovered in terms of Business Continuity. However, a lot of enterprises have been outsourcing their Disaster Recovery Center. Therefore, it is highly possible that the information system can not work well and result in the discontinuity of business when any trouble arises because of seperated plan of Business Continuity and Disaster Recovery. The study draws critical success factors for successful disaster recovery through researches of 42 documents. Then, factors are reviewed through interviews with consultants, experts of Business Continuity Plan and the information system officers of domestic banks. Domestic companies can make use of the study when they develop or renew Disaster Recovery Plan or Information System in terms of Business continuity.

The purpose of this paper is to suggest the types of recovery activities and the major contents of preimpact recovery plan through theoretical review. Disaster recovery is to provide immediate support during the early recovery period necessary to return vital life support systems to minimum operation levels, and continuing to provide support until the community returns to normal. Disaster researchers distinguished 4 types in recovering from disaster as follows; an emergency period, a restoration period, a reconstruction period, and a developmental reconstruction period. And recovery measures are both short-term and long-term. Short-term measures are relief and rehabilitation and long-term measures include reconstruction. Finally, to design a preimpact recovery plan, we should define a disaster recovery organization that includes major stakeholders, identify the location of temporary housing, determine how to perform essential tasks, address the licensing and monitoring of contractors and retail price controls to ensure victims are not exploited, determine how recovery tasks will be carried out at historical sites, and recognize the recovery period as a unique time to enact policies for hazard mitigation and incorporate this objecive into the recovery planning process.

As the business dependency to information systems and the frequency of the large scale disasters increase, implementing the disaster recovery center has been a common practice. However, since there has been little quantitative decision method for the distance between the data center and the disaster recovery center, the distance decision has been commonly made by qualitative guidelines. In this research, the decision method for the optimal distance between the data center and the disaster recovery center is developed, using the cost analysis including the operation cost and the expected disaster cost. An illustrative numerical example is provided.

In the current business environment where dependence on IT has increased rapidly, the risk from disasters or cyber-attacks is also increasing. Business continuity, the ability to continue to provide service in the event of a business disruption caused by a disaster, is essential. In other words, you need to have a plan in place to keep your core business functions uninterrupted with rapid recovery within a predetermined Recovery Time Objective (RTO) and Recovery Point Objective (RPO) time frame. In this paper, we propose a disaster recovery system construction method that can minimize RTO and RPO to ensure business continuity. The system configuration adopts Tier 7 disaster recovery model, synchronous storage replication, hot disaster recovery site, and operation management automation solution. This ensures continuity of core business with virtually no data loss and minimal RTO and RPO.

To decrease the damage of infrastructure from the natural disaster, initial reaction and emergent recovery are important. But up to now emergent recovery has mainly focused on the situation notices owing to the lack of technical support. In this paper, we described a web-based support system for disaster damage recovery of facility and electronic documents for requesting support of recovery resources. Recovery methods are decided using the damage recovery scenarios based on the acquired damage information, and the allocated recovery resources information is delivered to the recovery resources owner using the electronic documents. This system could readily be used for disaster response and emergency recovery.

DRS (Disaster Recovery System) that was invested on a large-scale becomes obsolete when it is neglected for a certain Period of time. Also the DRS can not be accomplished through the duplicated computer systems. When a disaster happens, the normal operation is possible only if the processes that had been being done before the disaster recover without any loss. Therefore the DRS is not a IT project but needs an analysis of whole business Processes and business continuity plans. This paper analyze the present state of DRS of the domestic bank industry and suggests a remedy.
