Disaster Recovery of Online System Based on Cloud Computing

This article discusses the disaster recovery technology of online system based on cloud computing, mainly starting from planning a backup strategy to restore the transaction log, pages, files and file groups by page and data restore from a snapshot database. Timely data recovery and fault exercises with a holistic, multi-level data backup and disaster recovery technology could protect the security of the online system.

Research and Implementation of CDP Disaster Recovery System based on Oracle

The OraCDP disaster recovery system uses CDP disaster recovery technology based on the combination of block level, combining with the communication coupling between the underlying I/O and Oracle database. The experimental results show that the OraCDP system can not only maintain the normal operation of the original system without any negative influence, but also guarantee the recovery of data and service at specific time quickly, fully and accurately.

Customer Satisfaction Study of Disaster Recovery Based on IPA Model

As an important way of recovering data from disaster, disaster recovery technology has turned into a key issue of all the industries depend on computer software system. IPA model is used to analysis customers’ satisfaction of disaster recovery outsourcing, the main factors are captured and analyzed. It is helpful to improve service quality, customers’ relationship and customers’ satisfaction.

General Discussion on Prevention Technologies of Network Security

Definition of network security is stated first. Network security threats; roughly including network connection threat, physical environment threat, authentication treat, malicious programs and system vulnerabilities, which can be further divided into more detailed categories. 8 prevention technology and strategies consisting of physical security means, firewall technology, intrusion detection, information encryption technology, vulnerability scanning, antivirus software, disaster recovery technology, and honeypots and honeynet technology are elaborated to try to form a general discussion of the security prevention structure. In the end, we propose that all of these technology and strategies should be organically combined and enterprises should pay more attention to network security rather than expanding production uncontrolled.

Research on Security and Defense Technologies in the Cloud Computing

The positive factors of the cloud computing: the great commercial value, the cheap and convenient use, has been recognized widely. But there are many risks on security. These security risks will greatly restrict the development of cloud computing. Cloud security risks such as: the cloud platform is easily vulnerable, cloud resources is easily abused, the cloud platform data is accessed by unauthorized user or the data is missing, the violations in the network is difficult to trace and survey, and the service providers replacement will affect the migration of the users data and services. So we research the virtualization technology, data backup and disaster recovery technology, encryption technology of data storage and transmission, the authentication technology of service providers and users, risk assessment, and legal constraints and safety training. Our research is strived to obtain a secure cloud computing environment.

Research of Cloud Storage and Data Read-Write Technology

Cloud storage is a promising market. In this paper, cloud storage technology and cloud data read-write technology is researched. Cloud storage has a four-layer structure model. Cloud storage uses disaster recovery and backup technology to improve the availability and reliability of the system. The request of data read-write in cloud storage is a temporary URL, which is constructed according to the algorithm. Send read-write request through push sequentially, and write by transfer between the primary chunks with the copies. The efficiency of cloud storage depends on the number of serves and clients. In order to improve the efficiency of data reading and writing, there is proposed three envisaged.

Application of Disaster Recovery Technology in Power Grid Dispatching Automation System

With the increasing expansion and complexity of the power system structure, the operational reliability of the power grid dispatching automation system has become increasingly demanding. The data’s rapid growth and requirements of high availability and security stimulate the development of the disaster recovery technology which has become a key factor of IT infrastructure. This article describes the disaster recovery technology in details from the measure index and level classification of disaster recovery, and analyzes its implementation process and importance by taking the disaster recovery in the power grid dispatching automation system as an example.

Review of Disaster Backup and Recovery Technology of Information System

Disaster backup and recovery is an important approach for system security and reliability,which can be used as an important support for information assurance in the development policy of China informationization.The measurements used for assessing the performance of disaster-tolerant systems are introduced firstly.The key technologies and realization methods of data-level disaster tolerance,system-level disaster tolerance,and application-level disaster tolerance are then summarized.Three future directions of disaster backup and recovery techniques are presented,which is the service-model shift from the data-storage-center to application-service-center,the architecture shift from a centralized structure to a shared mode based on the combination of distribution and virtualization,and the application mode shift from an isolate and specified system to a comprehensive service system,respectively.
