USENIX 2002 Annual Conference - Technical Program Abstract

Engineering a Differencing and Compression Data Format

David G. Korn and Kiem-Phong Vo, AT&T Laboratories - Research


Compression and differencing techniques can greatly improve storage and transmission of files and file versions. Since files are often transported across machines with distinct architectures and performance characteristics, compressed data should be encoded in a form that is portable and efficient to decode. This paper describes the Vcdiff encoding format for differencing and compression data and presents an empirical study showing its effectiveness.
