In this work, a method for backup and restoring data is proposed. The data is stored on different remote disks and temporary or permanent loss of access to any n of them appears. The high efficiency of the proposed method is achieved by using a theoretically proved minimum number of backup copies of the data, which is equal to the number of the disks to which access has been lost. The mathematical idea of proposed method and procedure for recovering of data from access lost storage unit are described in details. A numerical example for developed recovering procedure are given. The theoretical and experimental effectiveness evaluation of the proposed method is demonstrated as well. The proposed method is aimed to ensure a high level of survivability of system of distributed data storage.
