FIELD: data processing and storage.
SUBSTANCE: invention relates to arrangement of data storage on network nodes. Method and system for storing data on network nodes, in which on each computing device (CU) associated with the control object, setting the operation stroke, obtaining on the control object a set of real-time data, each cycle is stored in shared random access memory CU in an array of circular buffers, stored on the long-term memory device changed from the previous cycle of operation CU data, CU are combined into a computer network and are network nodes, real-time data of the last operation cycle of CU are transmitted to computer network from circular buffer arrays, simultaneously with receiving compressed data, receiving network node analyzing information obtained with such data on availability of compressed archive data on transmitting network node, and network node is compared with stored on receiving network node, and when detecting missing data, receiving network node sends UDP packet to sending network node with list of missing compressed archived data.
EFFECT: technical result is wider range of means.
