Abstract
Differential compression (aka, delta encoding) is a special category for data de-duplication. It can find many applications in various domains such as data backup, software revision control systems, software incremental update, file synchronization over network, to name just a few. This talk will introduce a taxonomy of how to categorize delta encoding schemes in various applications. Pros and cons of each scheme will be investigated in depth.
Learning Objectives
