摘要
随着Internet技术和信息数字化技术的迅猛发展 ,需要存储和处理的信息量十分巨大 ,出现了许多新的在线存储方案。仅用磁盘已经不能满足如此巨大的在线存储要求 ,磁带从脱机存档的角色逐渐变成在线存储介质中的重要一员。本文设计并实现了一种基于磁带的虚拟文件系统 ,屏蔽磁带物理访问细节 ,为上层应用程序提供编程接口 ,实现磁带信息的“按名存取”。该虚拟文件系统包括磁带文件创建、文件读取、文件更新、文件删除、文件拷贝、文件重命名以及磁带存储空间碎片整理等操作。
With the rapid development of Internet technology and information digitization technology, many storage solutions have been presented. Tape becomes more and more important in online data access. A new tape-based virtual file system, which hides the details about tape and provides API for applications, is designed and realized in this paper. This virtual file system realizes 'access by name', including tape file creation, tape file read, tape file update, tape file deletion, tape file copy, tape file renaming and tape defragment.
