how do I find windows backup feature on many servers?

Good day,

 I need to get the installed feature "Windows-Server-Backup" status on many servers ranging between 2008, 2008 R2, 2012, and 2012 R2. I believe my best approach is powershell, I know the following below will work. What I need is to have it reference a serverlist, then pipe those results of the servers in that list into a csv or txt file. Any help would be great, I am working on methods to do this on my end as well and will update if I make head way.

PS C:\> Import-Module ServerManager
PS C:\> Get-WindowsFeature windows-server-backup  | Out-File C:\Temp\WindowsFeatures.txt
