The Design and Implementation of a Data Backup System based on HDFS

This paper applied the technology of cloud storage for data backup,designed and implemented a data backup system based on the distributed file system HDFS.The system built a low-cost and scalable distributed cluster using the technology of cloud storage,and met the users' demand of data backup/recovery.It also further improved the performance and security of the system through a combination of compression,encryption and other technologies.Experimental results showed that the system has certain advantages in the aspect of security,scalability and economy.
