In SQL Server 2022, a new backup compression algorithm was introduced known as QAT_DEFLATE. This article demonstrates the installation of the Intel® Quick Assist Technology Driver, which is required to use this algorithm.
Let me demonstrate the installation step by step.
Installation:
Step 1:
The first step is to download the driver, which can be downloaded from here. Currently, QAT 1.7 version is available for download. You need to download whatever latest version is available. It will be downloaded as a zip file.

Step 2:
Once it is downloaded, you just need to extract it and you will get below files in the respective folder.

Step 3:
You need to run QatSetup file in order to install it, a warning message as shown below will appear which is fine, since you are installing it on a server which does not have any Intel QAT supported hardware, so you just need to click Yes to proceed.

Step :4
Click on accept the terms and then click Next button to proceed.

Step 5:
Now, it’s ready to be installed, click on Install button to proceed the installation.

Step 6:
Once the installation is completed, “install wizard completed” will appear and QuickAssist Technology is ready to be used.

Step 7:
Once you click on Finish button, installation summary will pop up, which shows the status of the installed components. Some of the components are not installed, since you don’t have any QAT supported hardware on this server as mentioned earlier.

Conclusion:
I found the installation pretty simple & easy; do let me, how did you find it.
