Working Deduplication files for Microsoft Windows 10

Thanks! working fine in LTSC.

 

I downloaded the package for 1809. Ran the commands in install.txt and all went fine and I have now the ps commands installed.

When I try to run enable-dedupvolume f: command, result is:
HRESULT 0x80004002, No such interface supported

Any ideas? I have tried to run enable command to empty volume, volume with files and so on. Always same error. Do I need to do something else that was not mentioned in install.txt file?

 

Hi,

i got the same problem. Did you ever find a solution?

 

Thanks to you, I'm now successfully deduping my 2TB backup drive.

I guess we should all vote in MS feedback here: aka.ms/AA1hljj, no?

 

Does anyone know how ReFS compression, introduced with Server 2019, differ from NTFS compression?

What's new in Storage Spaces Direct:

• Deduplication and compression for ReFS volumes

 

I have no idea what happened, but it began working somehow. Maybe I was missing a boot or something..?

Hi,
Just to let you know that I have this problem because of Boxcryptor in my case.
When I close Boxcryptor, every Powershell command run correctly

 

More issues.. I have storagespaces drive, which I deduplicated. Now I wanted to remove dedup, I did unoptimozation and gc, storage spaces shows now 11tb of data usage, while real amount of data is 6.6tb. Any idea how to get storagespaces to see correct usage data..?

 

run garbage collection

 

How do we get the package files for dedup? I want to grab them for 18362 which looks like it maybe the next 19H1 release.

 

I'd like to know the answer to this question as well. All of my digging has resulted in nothing.

Working 18362.1 Dedup files pulled from Server 2019 1903. For future reference, the Chunklibrary and VdsInterop packages ARE NOT needed to get data deduplication functioning.

***Works for all 18362(1903) and 18363(1909) builds***​

Pack can be found here...

Oops, good catch. It's fixed now.

 

apologies if I missed it somewhere in this massive thread, but what is the behavior of dedup'd volume during major upgrades.

If I install and enable it on 1809, come 1903, what happens?

 

You wouldn't be able to access files on the deduplicated volume unless you properly disable deduplication on the volume first...

Code:

PS > Start-DedupJob -Type Unoptimization -Volume x: (where x= the deduplicated volume)
PS > Disable-DedupVolume -Volume x: (where x= the deduplicated volume)

Or in the case of going from 1809 to 1903 you can install the dedup set I provided to maintain access to the feature and dedup'd volume/s.

 

Thanks for the clarification.

 

It blows up... nothing. You have to install the 1903 dedup to access your files from a previous version.
