For the upcoming version of Windows, new critical features are being worked on including cluster support and support for one way replication. The core engine is also being reworked to provide dramatic performance improvements. We will also soon be starting major improvements for Windows 8 where we will be including innovative features which will revolutionize file access in branch offices

Some of the features include:

Distributed File System Replication (DFSR) service: A multi-master replication engine set up for folder synchronization across multiple servers. This may be something we will be seeing in Windows 8 Server.
Major improvements in BranchCache: BranchCache was a new feature developed in Windows 7. Basically when data from an intranet website or file server is accessed, it caches those files locally so the next user can access them more quickly. Major improvements can be expected for BranchCache.

Microsoft’s explanation

DFSR is Microsoft’s premier file replication engine and is an integral part of our branch office strategy and File Server role. It can scale to thousands of servers and replicate hundreds of terabytes of data. We have shipped the technology that powers file sharing in Windows Live Messenger, Windows Meeting Spaces (Vista) and Branch Office replication in Windows Server 2008 which has strong customer deployment. DFSR technology saves MS-IT and our customers more than 80% WAN bandwidth by using advanced On-The-Wire differential compression,” the software giant adds in the job posting.
