| 摘 要： | 提出并实现了一种基于P2P的数据备份与恢复系统。系统采用最优数据分配策略将块数据上传到响应节点，利用分组对等互备冗余方式来提高备份数据的可靠性。当文件丢失时，系统利用多种安全方式来确保恢复文件的完整性和真实性，利用备份索引机制来提高恢复效率。仿真实验表明，文章提出的方法能提高备份文件的上传速度，增强备份系统的可靠性。

| Abstract: | A P2P Backup and Restore System is presented and realized. Block data is transferred to answering peers through optimal data assignment mechanism. In order to improve the reliability on the backup file, the system adopts grouping P2P mutual replication redundancy method. If a file is lost, the system will utilize mutiple security manner to ensure the integrity and factuality of the recovered file. Meantime, it adopts the index mechanism of backup to improve the recover efficiency. Simulation results show that the methods can improve the upload velocity of backuping file, and enhance reliability on backup system. |
