Abstract: The article analyzes the effectiveness of increasing the reliability of distributed data processing systems working on the basis of computer networks by means of data reservation and recovery. The article describes the two variants of data recovery, which was destroyed in one of the computer network nodes. It was described two basic strategies (B-1 and B-2) of data recovery in distributed data processing systems. Optimization problems were described for data recovery optimization with different optimization criteria.

Keywords: data processing systems, computer networks, data recovery reservation, data recovery strategy, optimization problems.
