The article describes the optimization of the process of disaster recovery of information infrastructure services by implementing the ability to restore service functionality without requiring a full recovery from backup storage. It outlines the criteria and parameters of the network that have a critical impact on recovery in the event of emergencies, allowing for the assessment of the solution's effectiveness in post-disaster recovery.

The development of states-transitions model is an important stage in the technology of
the development of the discrete-continuous stochastic models of fault-tolerant systems. There
is a known method of developing the states-transitions model, which is based on an algorithm
of constructing the state-transitions models out of so-called “structural-automaton model”.
This method is implemented in a software tool prototype called “ASNA”. If structuralautomaton
model is errorless, resulting states-transitions model will be errorless as well.

Designing of radio-electronic systems of responsible purpose with hardware-software implementation involves the mandatory provision of their property of fault-tolerance. The property of fault-tolerance are provided by the use of fault-tolerant systems. For these fault- tolerant systems at the stage of system engineering design it is necessary to solve the problem of reliability structural-parametric synthesis. A designer must have a high degree of adequacy of reliability models of fault-tolerant systems with different configurations to solve such a task.
