Configuring Nano Server and Dedup

Data Deduplication is a feature of Windows Server since Windows Server 2012 that can reduce the on-disk footprint of your data by finding and removing duplication within a volume without compromising its fidelity or integrity. For more information on Data Deduplication, see the Data Deduplication Overview. Nano Server is a new headless deployment option in… Read more

Data Deduplication in Windows Server 2016

Since we introduced Data Deduplication (“Dedup” for short) in Windows Server 2012, the Dedup team has been hard at work improving this feature and our updates in Windows Server 2016 are no exception. When we started planning for Windows Server 2016, we heard very clearly from customers that performance and scale limitations prevented use in… Read more

New Support for Windows Server Data Deduplication in Limited Local Hyper-V Configurations

A popular request from our customer base for Windows Server Data Deduplication has been to support the Hyper-V scenarios (i.e., VDI and virtualized backup) on storage local to the Hyper-V server. This “hyper-converged” configuration uses a single server or cluster for hosting the VDI or virtualized backup guest workloads and dedup is enabled on local… Read more

Large Scale Study and System Design for Primary Data Deduplication accepted by USENIX

Microsoft Research (MSR) and the Windows File Server team worked together to build a new Data Deduplication feature in Windows Server 2012. This feature came from 2 years of collaboration with MSR on the design. The development of the architecture and the algorithms we use for deduplication was driven, in part, by analysis of data… Read more
