METHOD AND SYSTEM FOR DISTRIBUTED STORAGE OF RECOVERED DATA WHICH ENSURES INTEGRITY AND CONFIDENTIALITY OF INFORMATION Russian patent published in 2022 - IPC G06F11/08 G06F12/16 

FIELD: data storage.

SUBSTANCE: invention relates to a system for distributed storage of recoverable data and a method for distributed storage of recoverable data. The method for distributed storage of recoverable data with information integrity is performed by at least one system, which contains a plurality of storage nodes connected by a network and storing data in the form of extents, data service (DS) agents for managing extents, metadata service (MDS) agents for managing metadata , related to nodes and extents, and cluster manager (CM) agents. The method consists of the following steps: generating a checksum for each data extent; detection of a node failure in the system by one of the CM agents or a disk failure in the system by the DS agent; notifying DS or MDS agents of a failure; formation by independently notified DS or MDS agents of a recovery plan for data extents affected by the failure; and collectively restoring the affected extents based on the generated plan in the previous step using checksums, with each node including a plurality of disks; and a disk failure is detected by the DS agent based on the disk error rate.

EFFECT: improving the reliability of data recovery.
