Persistent data layer
Microsoft Windows Server native deduplication and compression can be set for StarWind virtual devices formatted as NTFS.

Windows Server 2019 Deduplication only happens in the persistent data layer and not in the cache. The cache is not accessible from the file system and so deduplication cannot be applied to it.
