Business continuity (BC) can be achieved by providing information systems that feature measures for enabling recovery from a disaster event by meeting RTO (Recovery Time Objectives) and RPO (Recovery Point Objectives). Therefore, it is necessary to evaluate the current vulnerability status of the information system by applying effective measures based on cost efficiency and by accurately assigning the priority of each component. This paper describes the methods of applying effective BC measures of information systems, specific details of these measures and the work required for the proper operation of backup systems, as well as the managed service for implementation of the BC measures.
