Design the Desktop Backup System Based on Cloud Computing

Based on extensive use of cloud computing, combined with various backup strategies, achieve a backup client running on the user´s desktop. The users who used cloud backup confront with the diverse cloud storage interface, directories and large files backup trouble. Based on the SNIA cloud storage model, compared with diverse interface from several cloud storage vendor, a cloud interface layer which shields the difference cloud storage interface is designed. Mapping the file system directory hierarchies and cloud storage data model, using hierarchical transmission implements directories backup. Though extending the file metadata information to achieve full backup, incremental backup, differential backup. Using breakpoint transmission to realize big files backup. Finally. the backup client performance test results show that the technology achieve a good performance.
