Deduplication is a powerful feature that helps you to reduce physical storage requirement. Windows Server 2012 and Windows Server 2012 R2 are now capable to enable this feature on a data volume.
I have done some testing and now I am going to enable this feature during my server refresh project on all file servers that are being migrated. Part of the migration is to create a SCCM program or task sequence to run this after the server has been migrated.
Import-Module ServerManager Add-WindowsFeature -name FS-Data-Deduplication Enable-DedupVolume G:\
I have already seen reduction between 30 to 40% on a production file server. Today I have enabled this on my SCCM server to reduce disk space so I can add more installation images without expanding the storage on a private cloud provider.
