摘要
针对目前云存储系统主要提供文件备份的现状,提出了一种面向云存储的归档方法,该方法将不活跃的文件数据以归档的形式存放在云端存储系统,并在客户端保留其存根信息以供读取时使用,从而不仅大大节约了客户端存储空间,改善了客户端性能,而且实现了对用户透明的归档数据访问.
Aiming at the situation that current cloud storage systems mainly focus on file backup,this paper presents a cloud storage-oriented archiving approach.By storing inactive file data in cloud storage systems in archival form and leaving its stub information on clients for the use of read,this approach can not only save storage space on clients and improve the performance,but also implement transparent user access to archived data.
