* Linux Data de-duplication

Data de-duplication is a effective way to reduce large storage needs by eliminating redundant data, a hot demanded feature for virtualization OS image sharing and efficient data storage backups. It's really valuable to add data de-duplication support to Linux filesystem, however the feature is quite challenging too. How to get it right? What's the performance impact? Block level or file level? On the fly data de-duplication in filesystem or background userspace de-duplication?
