Modern approaches to substantiating the failure-tolerance indicators of the automated control system of the operational command center of the Armed Forces of Ukraine are based on the fact that any process of accumulating, collecting and storing information is invariably cyclic in nature. This essence determines the need to justify the indicators that allow data to be backed up in the automated management system. Such indicators of fault tolerance of the automated control system of the operational management center include: target recovery point - RPO; target recovery time - RTO; continuity of IT-services. The given indicators determine the effectiveness of the information support of the automated management system, which consists in providing management with timely and reliable information. This is especially relevant in the conditions of full-scale armed aggression of the Russian Federation against Ukraine and requires improvement of approaches to ensure the resilience of the automated control system of the operational command center of the Armed Forces of Ukraine. The model of IT-service continuity threats developed in the article makes it possible to compare classes of threats with their frequency of occurrence and typical means of protection. Based on them, it is possible to compare the corresponding indicators of scheduled recovery, in particular backup and archiving of data on a remote server (Crossite backup). In addition, the work considers approaches based on the application of financial indicators of the effectiveness of automation processes (Total cost of ownership), which allow to estimate the total costs of information technologies (equipment, tools, processes of supporting information systems.
