Disaster Recovery Backup and Privacy Protection Algorithm of Hotel HRM Information System

In this study, a high-star hotel is used as a case to study the impact of informatization on hotel human resource management. For the hotel human management system data with many types, large quantities and high security requirements, the data disaster recovery backup should have scalability and privacy protection. The results show that: First, from an overall point of view, the current human resource management in the hotel industry has fully entered the information age, and the overall trend will continue. Secondly, in terms of specific applications such as recruitment management, training management, personnel management, etc., combining it with cryptographic technologies such as AONT and threshold secret sharing, a new power data disaster recovery backup scheme is proposed, which is implemented on the open source blockchain platform.

A failure detection method of remote disaster recovery and backup system

Failure detection is one of the basic functions of building a reliable disaster recovery backup system. Aiming at the application-level disaster recovery backup failure detection problem, this paper analyzes the remote disaster recovery center architecture and failure detection hierarchy, and predicts the arrival time of cross-domain heartbeat information through the back propagation neural network based on particle swarm optimization (PSO-BP). When the actual timeout is reached, the active Auxiliary Detection (AD) is used to improve the correctness of failure detection, and finally the effectiveness of method PSO-BP-AD is verified through simulation.

Renovating blockchain with distributed databases: An open source system

A blockchain is a decentralised linked data structure that is characterised by its inherent resistance to data modification, but it is deficient in search queries primarily due to its inferior data formatting. A distributed database is also a decentralised data structure which features quick query processing and well-designed data formatting but suffers from data reliability. In this work, we showcase ChainSQL, an open-source system developed by integrating the blockchain with the database, i.e. we present a blockchain database application platform that has the decentralised, distributed and audibility features of the blockchain and quick query processing and well-designed data structure of the distributed databases. ChainSQL features a tamper-resistant and consistent multi-active database, a reliable and cost effective data-level disaster recovery backup and an auditable transaction log mechanism. The system is presented as an operational multi-active database along with the data-level disaster recovery backup and audibility features. A comprehensive experimental evaluation is performed to demonstrate the effectiveness of the system.

A real-time data backup model and methods based on peer-to-peer network

Real–time backup data transmission over the internet can guarantee system availability using the self–organisation features of the internet during a disaster. We present a real–time disaster recovery backup model based on peer–to–peer (P2P) streaming with considering the reliability and security. The key metrics, which are recovery time objective (RTO), recovery point objective (RPO), and predicted channel delay of the P2P disaster recovery backup model, were analysed. Then the backup methods were described based on a P2P network, which consists of a node–joining mechanism, data sending and receiving mechanism, etc. To ensure transport channel redundancy, we designed a node conflict resolution algorithm. We also optimised the algorithm in terms of node distance, historical information, useless nodes traffic, etc. Finally, simulation experiments were conducted. Compared with a backup method using a leased line, the methods can avoid the conflict between fixed bandwidth and dynamic changes in backup data size and the single point of failure of a leased line.

Application of Virtualization Technology in Nuclear Power Plant

Virtualization is the basic physical computer hardware that related modules in the virtual basis rather than the real independent operation to realize the simplified and optimization management of resources. This paper reviews the historical development of virtualization technology and the compare of mainstream realization manners which are the basis for comparative analysis. At the end of this paper we study a feasible mean for the disaster recovery backup solution in nuclear power plant.

A Comprehensive Security Strategy Applying to the Total Life Cycle of Cloud Computing Data Center

Aiming at the security issues of cloud computing data center, the systematic security construction architecture of cloud computing data center is proposed. By surrounding the key aspects of security construction, such as infrastructure security, virtual security, cloud authentication and authorization, data isolation and protection, cloud platform and cloud service security, security operation maintenance, cloud computing platform migration, and disaster recovery backup, the security architecture constructs a multi-level, multi-angle tridimensional defense system in depth. It ensures the life cycle security for resource services of the cloud computing data center. Many key problems are further discussed in detail, such as the problem of data storage security, security domain isolation, cloud computing platform tenants accessing, and terminal accessing. This paper provides reference for the security construction of cloud computing data center, and gives guide to the implementation of the relevant security measures.

Dinosaurs, hype and the infosec bandwagon

In the June Editorial, in illustrating a comment about the need to be certain that your disaster recovery back-up site is actually available, a quote was made from newspaper reports about a disaster the EDS computer centre in New Jersey suffered and the alleged nonavailability of the Comdisco back-up site. Due to the nature of the disaster, EDS required a longer term production environment, not the short term recovery site they had contracted for, and released a communication to customers and the press which inadvertently misrepresented Comdisco's role in their disaster recovery efforts. EDS has subsequently issued a statement to the effect that Comdisco had made fully available the contracted hot site and cold site back-up services and have continued to hold the sites available to EDS should they be required.
