Update Feb 11, 2020

In my First Blog post here Part1 I showed you how to set up Windows Deduplication on Server 2016. This second series will show you my production results and what I gained in space-saving

I estimated 18.5% in savings in the first post. However, I got 23% back, I think that is good in my opinion

I enabled Windows Deduplication on my production File Server Part1

Here is the drive space before, windows deduplication was running.

Ever so often I would run get-dedupstatus to give me an idea of what I am getting back

After Deduplication was run on 4TB Drive. As you can see I got back some good space

Now I wanted to take it one step further, and shrink the VHDXs. (Running it manually this time around)

Before

I got back just a tad over 1 TB and some change overall. I take that as a win for now. Soon very soon, I will be moving a lot of this to Nutanix files, then we can see the difference if any 😊 of Those who use Nutanix AHV and Nutanix Files understand the awesomeness it offers. 

Nex day Checks on February 12,2021

Let’s check on the Environment, and confirm logins are not slower, and that the schedule is set incorrect nothing is running during the day.

My schedule is at 10pm = Check

I can confirm it’s not running and when the last time it ran is = Check

Monitoring the event log

“Monitoring the event log can also be helpful to understand deduplication events and status. To view deduplication events, in File Explorer, navigate to Applications and Services Logs, click Microsoft, click Windows, and then click Deduplication.”

“If the value LastOptimizationResult = 0x00000000 appears in the Get-DedupStatus |fl Windows PowerShell results, the entire dataset was processed by the previous optimization job”

Start time

Finished time

Citrix VAD (Fslogix) Login times. 1.6 seconds to attached the FSLogix profile.

Checking in Control up and things seem to be as they should before this was enabled. If you don’t have Control up, you can use Director. You can use the script as well to achieve some login measurements with just powershell

As you can see, these are just some built in tools you can use. There is really no reason why you should not have this setup. Always test things and make sure you understand what it is that it’s doing, so you don’t break things
