Abstract: Cloud storage provides storage services to users via Internet. They provide lavish interfaces for different applications. Online backup is the most developed application based on cloud storage. Most past studies focus on functional characters and price per GB. But there is not much consideration about performance evaluation. In this paper, the authors present a method to evaluate the performance of different online backup services with clients. Because these clients do not prompt when the download/upload process starts and finishes, the authors capture the packets transferred between clients and the cloud storage provider. The authors evaluate the performance from the view of the end-user, comparing the upload and download speeds of different services. This method can help users find the best provider to accommodate their situation. The authors evaluate the performance of several cloud storage providers by analyzing the performance of different vendors in different times and different file type and size. From the performance results, the authors can expose which technologies are used in the cloud storage system to reduce the storage and network cost.
