摘要
随着传统行业电子化的速度日渐加快,电脑上的数据量与日俱增,数据备份领域面临的挑战也越来越大。传统备份因为需要大量的磁盘阵列作为存储介质,所以在成本控制上一直是个难题。针对该情况,结合云存储平台低廉的成本、高效的资源伸缩与利用率,研究在HDFS系统中加入新的重复数据删除技术,并对原有备份策略进行优化,设计出一种基于云存储中的重复数据删除技术的备份系统。最后通过实验,对改进后的方案系统与传统备份方案备份文件所占空间、时间等参数进行了对比。
With the speed of electronic of traditional industry gradually accelerating,the amount of data on the computer is growing,challenges in the field of data backup are also growing.Because traditional backup requires a lot of disk arrays as the storage medium,so the cost control has been a problem.For this situation,combined with the low cost of cloud storage platform,scalable and efficient resource utilization,research in HDFS system by adding new data de-duphcation technology,and optimize the existing backup strategy,design a cloud-based storage the deduplication backup system.Finally,through the improved scheme system and the traditional backup program backup file with useing less space and time parameters were compared.
