摘要

雲端運算目前已是學術研究的焦點議題，其商業性應用也逐漸成為趨勢。雖然，雲端運算中關於檔案資料之可用性、完整性是主要的研究主題，但隨之衍生的資料安全性議題卻逐漸演變為攸關雲端存敗的關鍵點。因此本研究擬架構一雲端檔案資料備援系統，以提高雲端運算下檔案資料可用性與降低資料完整性的安全威脅，達到企業使用者能夠信賴雲端運算之環境。再者，由於雲端運算導入初期，大多數的組織機構在將檔案資料從原本的資訊設備內遷移至雲端平台時，均面臨資料量太大衍生出網路頻寬無法負荷之情形，及以手動方式遷移數量龐大的檔案時極易出錯之困境。此外，在考慮功能之更完備、更易運用及更具商業價值的前提下，本研究特別將檔案資料遷移至雲端的功能，整合加入本研究建立之雲端檔案備援系統中，並加入提升資料安全性之設計，透過此資料安全之設計，以降低企業運用雲端環境時的安全疑慮和憂心、提升企業對雲端運算的接受度，並進而使雲端處處更易於推廣。

Cloud computing is already the major topic of the computer science research; its commercial application has become a new trend. File data availability, integrity are the major research topic in cloud computing. The security issues become the key of success while the information retrieval from the data deposit of the cloud computing environment. Therefore, this study is try to create a cloud backup system, in order to increase the file data availability, to reduce the integrity of security threats. This system can achieve the objective which users can believe the cloud computing environment. Furthermore, in the earlier cloud computing most of the business archives are migrated data from the local storage devices into the cloud platform. Such applications are confronted with the overloading of network bandwidth, and manually operation of data migration will induce the error easily. Therefore, the migration function for file data to the cloud platform system is constructed in a cloud environment in this research, and enhances the function to more completeness and easier to use. For the commercial application consideration, the proposed system developed the cloud file backup utilization to increase data security.
This research consists mainly of three parts: the first is described how to build an operating environment for Apache, PHP, Java program, the Linux operating system environment; the second is followed by the establishment the interface of a users to browse and download the backup files; Finally, there are some modules are presented in the design of the FTP server to migrate files, including the program module and communication cloud platform of redundancy department program modules. In this system, it integrated system environment, interface modules and associated files database structure. And these operations are expressed in a logical procedure of these programs. After the implementation and verification, the proposed system in this study can provide users with a security and convenience cloud backup system.
