The new deduplication in Windows Server 8 looks awesome, and it just might be the “killer app” for many business to start using Windows Server 8. The feature will make it possible for companies or servers that don’t use SAN/NAS with de-duplication to save disk space, alot if disk space. How much disk space you can save will depend on what kind of files you have on the disk. You have a utility you can use to calculate the savings, the tool are now only available when you have installed Windows Server 8 (sort of), but I am quite sure that it will be a downloadable and graphical tool in good time for the RTM release of Windows Server 8. The tool that are in the beta version of Windows Server 8 are a command line tool.
Yes I am running it on something else than Windows Server 8, it’s actually my Windows 7 computer. My next blog post will tell you how to run it on other Windows than Server 8. Be aware that all deduplication have the cost of hardware resource usage, so be sure to monitor your server to make sure that you don’t replace disk shortage with other system resource shortages. You might also use a dedicated server as storage server, remember that Microsoft now give away the ISCSI Initiator target for free. You can of course use Powershell with it, so it’s easy to automate the process.
