The Windows deduplication is a good choice for file shares that contain ordinary files. By that, I mean no active databases or other files that churn constantly. You can apply dedupe to any existing volume. You don't have to re-create or copy it Assume that you are using Windows Server 2012 R2 as a Server Message Block (SMB) file server, and you have data deduplication enabled. After it operates for some time (typically several days), the SMB Service becomes unresponsive, and clients lose connections to the server You also have to consider the load that deduplication will place on the server. Windows deduplication runs post process, which means that you can run a deduplication job at a time when the server is not under a heavy load. Even so, deduplication is CPU and I/O intensive, so you will need to take that into account In Windows Server 2016, Data Deduplication is a role that can be installed.

A number of features are built into.
What's Data Deduplication in Windows Server 2016? Files, which are stored to a disk volume and left there for several days (to ensure it's not fast-changing data), can be checked by a special process, splitting this data into small blocks, named chunks (32 KB - 128 KB) and then analyzed chunk by chunk. The system preserves unique blocks only, moving them into a chunk store and leaving. 6) BranchCache™ : Another benefit for Windows is that the sub-file chunking and indexing engine is shared with the BranchCache feature. When a Windows Server at the home office is running deduplication the data chunks are already indexed and are ready to be quickly sent over the WAN if needed. This saves a ton of WAN traffic to a branch office Ok but I cannot see a MS site or a way in Windows to do that. Anyway not helping this issue. So to me you need to revert to the previous version of Windows whilst you still have time and then undupe the drive, or mount the drive in a Server 2016 and recover the files, or mount the driver in a Windows 10 1607 with dedupe enabled and again recover the files
Data Deduplication is a feature of Windows Server 2016 allowing to optimize free space on a volume by investigating the data for duplicates. When a duplicated element is found, it gets replaced with a pointer to a unique copy of that chunk, thus freeing storage space To configure data deduplication, open Server Manager, choose File and Storage Services, click Volumes, right-click the volume that you want to deduplicate, and then choose Configure Data Deduplication. The Deduplication Settings page appears This issue occurs because deduplication metadata that's stored on the compressed volume root becomes corrupted when a process writes in-place to a file on the deduplicated volume. The deduplication metadata that is stored on the compressed volume root is located under the System Volume Information (SVI) folder.
