Data Backup and Recovery Based on Data De-Duplication

This paper via compares data de-duplication with other data storage methods, analyses characteristics of data de-duplication and applies the technology to data backup and recovery. Highlights special process of asynchronous backup and recovery based on data de-duplication. Data de-duplication can reduce backup volume, then save users data storage space, and cut the cost of storage, asynchronous backup makes it more reliable and controllable used in design process. Finally, it makes an analysis of the feature of backup recovery mode and its security problems, and gives improved advices.
