Research On The Backup/Recovery System Of Power Information Data

Power information industries, the Industrial chain complex, the amount of datahave the characteristics of confidentiality and huge. Therefore, data backup and disasterrecovery becoming more and more important. Deficiencies of traditional data backup isthat the large-backup-window, long-recovery-time and other issues. When productiondata corruption, the user will lose the characteristics of the data between the status of thebackup window. Continuous data protection technology has become efficient and securedata to solve the backup/restore effective means of management. This article is a specifictype for application software development article. The object of this paper is HBUbackup management software continuous data protection CDP module. It is be located ontop of the file system and database systems, and can run in the Power Corporation datacenter.In this paper, starting from network security, electrical information security, andcryptography knowledge, for the characteristics of Oracle manage data, design the powerinformation backup and recovery management system. Continuous data protection CDPmodule is based on block-level data changes automatically capture technology, to narrowthe backup time window, homomorphic encryption is applicated control data encryptionand decryption algorithms, so that, in the storage management data is not visible, toeffectively protect data. This paper from the the perspective of the softwareimplementation, introduce the overall composition of HBU backup software. And on thisbasis, the design is suitable for continuous data backup power information managementof information data protection CDP module. Detailed design the key sub-modules for thecontinuous data protection CDP module, including block-level data changesautomatically capture functional design, data cache module design, the application ofhomomorphic encryption for data encryption package module design and log moduledesign. And on this basis, analysis applies to power enterprise database storage protectionfeatures of CDP backup strategy.For Power Corporation data center construction target, design the overall powerdata center planning scheme and power data center backup service platform solutions.And carried out the backup and recovery functional test for HBU-CDP software modulesand HBU server software, HBU client agent side of software that software run on powerdata center backup service platform. According to the deployment and operation testresults indicate that this software management system can meet the Power Corporationdata protection requirements.
