【摘要】：當今企業(yè)大量的關鍵機密信息文件分布存放于員工的終端電腦，隨著筆記本電腦、移動存儲的普及，以及互聯(lián)網(wǎng)應用的發(fā)展，企業(yè)越來越關注自有知識產(chǎn)權(quán)的保護和內(nèi)部重要文檔的安全問題。一旦這些信息數(shù)據(jù)丟失或損壞，將造成難以估量的損失。企業(yè)采用數(shù)據(jù)備份系統(tǒng)備份重要的數(shù)據(jù)是解決數(shù)據(jù)損壞和丟失的唯一可行的解決方案。 對現(xiàn)有數(shù)據(jù)自動備份系統(tǒng)基本原理和系統(tǒng)結(jié)構(gòu)進行了分析，并對與實現(xiàn)數(shù)據(jù)自動備份系統(tǒng)相關的一些重要技術(shù)進行了深入研究。研究了數(shù)據(jù)備份系統(tǒng)的業(yè)務流程，設計了數(shù)據(jù)自動備份和共享的系統(tǒng)的總體結(jié)構(gòu)。 設計并實現(xiàn)了一種數(shù)據(jù)自動安全備份及共享的網(wǎng)盤系統(tǒng)，它在遠程建立數(shù)據(jù)備份中心并通過Internet將數(shù)據(jù)備份到遠程服務器，同時改進了數(shù)據(jù)存儲和數(shù)據(jù)傳輸方面的安全性問題，還改善了備份方式和提高了系統(tǒng)的可用性，具有自動、安全、可靠的特點。 數(shù)據(jù)自動備份系統(tǒng)改進了數(shù)據(jù)備份方式，采用先進的增量備份技術(shù)，將數(shù)據(jù)備份到遠程服務器，，減少了網(wǎng)絡傳輸量。采用此技術(shù)可以只對數(shù)據(jù)的增量進行備份，而無需備份整個文件。使用文件冗余檢測和消除，對相同的文件只備份一次，消除了文件的冗余備份。這種備份方式大大減少了對Server存儲空間的占用，相同文件只在存儲空間中保存一份，同時，相同的文件不再多次重復備份也減輕了網(wǎng)絡壓力。設計了數(shù)據(jù)可靠傳輸安全功能。采用高效的數(shù)據(jù)加密策略，結(jié)合MD5一致性驗證技術(shù)，保障了關鍵數(shù)據(jù)在傳輸過程中的安全性和恢復時的完整性、可用性。數(shù)據(jù)共享系統(tǒng)，可以實現(xiàn)數(shù)據(jù)在系統(tǒng)中的對個人、部門及全局的共享。
[Abstract]:Nowadays, a large number of key confidential information files are distributed in the terminal computers of employees. With the popularization of notebook computers, mobile storage, and the development of Internet applications, Enterprises are paying more and more attention to the protection of their own intellectual property rights and the security of important internal documents. Once this information data is lost or damaged, it will cause incalculable loss. Using data backup system to back up important data is the only feasible solution to solve data damage and loss. The basic principle and system structure of the existing data automatic backup system are analyzed, and some important technologies related to the implementation of the data automatic backup system are studied in depth. The business process of data backup system is studied, and the overall structure of data automatic backup and sharing system is designed. This paper designs and implements a kind of network disk system which can automatically and safely backup and share data. It establishes data backup center remotely and backups data to remote server through Internet. At the same time, it improves the security of data storage and data transmission. It also improves the backup mode and the availability of the system. It is automatic, safe and reliable. The data automatic backup system improves the data backup mode and uses advanced incremental backup technology to backup the data to the remote server, thus reducing the amount of network transmission. This technique can only backup the increment of data without backing up the entire file. Using file redundancy detection and elimination, the same file backup only once, eliminating the redundant backup of files. This kind of backup method greatly reduces the footprint of the Server storage space, the same file is saved only once in the storage space, at the same time, the same file does not repeat the backup many times and also reduces the network pressure. The security function of reliable data transmission is designed. An efficient data encryption strategy and MD5 consistency verification technology are adopted to ensure the security and integrity and availability of the critical data during the transmission process. Data sharing system, can achieve data in the system of individuals, departments and the overall sharing.
