Design And Implementation of On-the-fly Compression File System

ABSTRACT

Disk Space scarcity has been amongst the problems that have persisted for a long time in the computer field. Data compression techniques have long been assisting in making effective use of disk network and other utilities. Most compression utilities however require explicit user intervention for compressing and decompressing data. However, there are some systems in which compression and decompression is done transparent to the user. This seminar describes a generic file system for Linux Kernel with the feature of on-the-fly compression and decompression in a manner that is transparent to the user. Some experimental results are discussed, which compare such file system with ext2fs, the native file system for Linux.
