The Research And Design Of Net Storage System Based On Cloud Storage

Data security become more and more important nowadays, data backup is the most direct and effective data security strategy, and remote backup is more security than local backup, which is used widely nowadays. The products which provide the remote backup service is not only expensive at present, but also the data security is not guaranteed. The users deploy the backup service by themselves costing too much. Therefore, the development of a high-performance, low cost remote backup system has the important theory significance and application value.With the rapid development of cloud storage and the current outstanding performance of Amazon S3, in the past year, the paper is committed to develop a synchronous network storage systems to satisfy user needs, first, this paper makes a in-depth research and analysis for the foreign related products and summarizes advantages and disadvantages in security and performance, Second with a deep research about the related technology and seven months internship experience in the department of cloud storage in borqs company, I devise a new synchronous network storage system structure with the control information and data information process differently, and gives detailed descriptions of the various parts and detailed implementation.This dissertation makes a deep analysis for remote file synchronization algorithm, and put forward new fast remote file synchronization methods. In storage, the dissertation devises an efficient storage solutions and appropriate solutions for guarantying the security of data and user information. Nowadays, many people usually work on multiple hosts, the dissertation designee a new solution which multiplies host can synchronization automatically. The user can share the file according their needs. The system cans automatically monitoring the changes in file, and then automatically makes synchronization with server and other hosts.
