Configuring Windows Server

 Data Deduplication Storage expenses can be reduced by using data deduplication, also known as Dedup. When enabled, data deduplication optimizes the available space on a volume by inspecting data and finding duplicate parts. Such duplicate parts could simply be kept once and optionally compressed for additional savings. Not only that, but it optimizes redundancies without compromising data fidelity or integrity.

To configure data deduplication, follow the steps mentioned below.

Instructions to configure data deduplication on the volume of your choice and install the deduplication feature on your server Enable it. Make sure that the deduplication status is correct. We will describe them in detail.

1. Installing the Data Deduplication feature on your server 

We will first install the Data Deduplication feature on your server. To do so, follow the steps mentioned below.

• Launch Server Manager on your computer.
• Then, click on Manage > Add Roles and Features.
• Once you have clicked Next, from the Installation
•  Type drop-down menu, choose Role-based or Feature-based Installation and then click Next.

When you get to the Server Roles panel, expand File and Storage Services, then go to File and iSCSI Services, select Data Deduplication and finally click on Install.

When the prompt appears, click on Add Features But finally finish the installation step.

You can also install Data Deduplication via PowerShell. All you would have to do is open PowerShell as administrator and run the following commands.

Data deduplication can be installed with the following command from a server running Windows Server 2016 or later or from a PC running Windows with RSAT installed. FS-Data-Deduplication can be installed with the following command. Install-WindowsFeature -ComputerName -Name run the command Below is a list of whether you can remotely connect to the server using PowerShell Remoting.

The command will look like this: “Enter -PSSession -ComputerName dism /online /enable “-feature /featurename:dedup-core /all 

2”. Enable data deduplication for the selected volume and configure it. Now after installing the feature we can enable it on the selected volumes. How to do it is described by following the steps below: To upgrade the server go to server manager and click on Upgrade and then choose Configure Data Deduplication. the invisible menu next to Data Deduplication and select General Purpose File Server Enter the number of days after which files will be duplicated in the “Duplicate file older than – Custom file extensions to delete” field or click on the Add button to add an entire folder. To delete a folder you need to browse for it and then select it To configure the schedule according to your organization’s demand click on Set Deduplication Schedule and then adjust the settings.

Data deduplication should not be a high priority task, therefore we suggest you keep the Enable Background Optimization option checked.

You should also turn on Performance Optimization and set it for a time of night when you don't mind resource consumption.

A second time window can be done using the Performance Optimization schedule. When you are happy with the schedule, click Apply > OK.

Click Apply > OK.

You can also do this by using PowerShell to create a deduplication policy on a designated drive using the following commands: Enable-DedupVolume-Volume-UsageType. This will do it yourself.
