I am using little snippets to detect server roles with powershell and I am having some issues getting results ommited.

My Code: 

Import-module servermanager ; Get-WindowsFeature | where-object {$_.Installed -eq $True} | format-list DisplayName

There here you specific which role to check:

Import-module servermanager ; (Get-WindowsFeature -name hyper-v).Installed 

However whenever I try use the role "Backup" I get no results. I have also tried Backup-Features, Backup-Tools,Backup-cmdlets as specified at: https://technet.microsoft.com/en-us/library/cc732757.aspx

If I try the other roles they come back either True or False, but Backup doesnt display any results, could this be a bug in the module?

Have you tried 

Get-WindowsFeature *backup*

As the actual name looks to be Windows-Server-Backup

Try not typing everything on  one line.

Import-moduleservermanager
Get-WindowsFeature -name '*backup*'|select name,installed|ft -auto

Does that mean I have to filter out the description if I want to create an IF statement based on whether a specific role is installed or not. Because previously it would only say true or False

What role are you asking about?

This works just fine:

Get-WindowsFeature -name backup|select name,installed|ft -auto

Hmm, what version of powershell are you running? I think mine needs to be updated to work

It works on all current versions of PowerShell.

Tried this on 3 different servers and I am receiving no output.

Get-WindowsFeature -name backup|select name,installed|ft -auto

Works fine for the rest of us.

Perhaps you are not an admin?  Perhaps you are not running elevated?  Perhaps you have a bad installation?

There are many reasons that things fail.  The answer is correct and works. 

This will not work on any workstation or any server pre WS2008R2.

Tested this on:

(3) Server 2012 Std's - Didnt work

(2) SBS 2011's - Worked

(2) 2008 R2's - Worked

I am curious as to why its not working on 2012

Backup is not on WIndpws Server 2012.  Use this:

Get-WindowsFeature Windows-Server-Backup

That worked, is there any way to make it only return a true or false value? So I could use something like

if $role = false then fail

PowerShell 101

if( -not (Get-WindowsFeature Windows-Server-Backup).Installed){
     Write-Host 'Not installed'
}else{
    Write-Host 'installed'
}

That worked, is there any way to make it only return a true or false value? So I could use something like

if $role = false then fail

Test on the Installed pro
