REPLICATION, REDUNDANCY AND INFORMATION RECOVERY SCHEMES IN UNRELIABLE DISTRIBUTED SYSTEMS
Vladimir Vasil'evich Kul'ba, Sergey K. Somov · RSUH/RGGU Bulletin Series Economics Management Law · 2017
The article is devoted to the problem of increasing the reliability of distributed data processing systems operating on the basis of unreliable computer networks. The situation is considered when, in addition to placing replicas and reserves of data sets in nodes of a computer network, data recovery methods are used in case of its destruction. The conditions under which it is advisable to use the closest node or archive of magnetic carriers as a redundant reserve or an undisturbed operational reserve are analyzed. The problem of determining the optimal scheme for reconstructing the destroyed replicas and the reserve of data sets is considered.
