A Low-Complexity Fault-Tolerant Document Storage System

Abstract

Fault-tolerant systems are those that continue to work properly even when faults occur. Distributed systems for files storing are susceptibles to faults, these failures can lead to loss of files completely, for this reason, these systems require strategies for recovery from failures. In this paper, a low-complexity distributed system for storing files in the cloud with fault tolerance is proposed. Files are stored in blocks, dispersed in a set of 7 servers and the reconstruction process is carried out using any combination of 6 as the proposed model generates redundancy blocks using parity mechanisms. From the experimental results, the reliability, security, speed for dispersion, and reconstruction of the proposed system are shown.
