Disable client backup on Server 2012 R2 Essentials

New install of Server 2012 R2 with Essentials Role. Having problems with the Client Backup feature (and actually don't want to use it anyway). Is there a way to disable it via Group Policy, etc.?

I've read posts that say you can just turn it off from the Dashboard, but even that is not working reliably. I have one local PC that is connected to the Server but the backups fail, as it 'thinks' it is not connected. That also means that the link on the Dashboard to 'Customize Backup for the computer' does not appear, so there is no way to turn it off. I just want to disable it for current PCs and any new ones that join domain.

The connector needs to be installed and connected to manage backups. But it also *does" the backups. So if it is reporting "not connected" or is not installed, backups will not occur. They are intrinsically tied.

Cliff, Please re-read my post - your reply seems to ignore what I said.

Connector IS installed, it DOES show as connected on client PC, and in the Server Dashboard the client shows as ONLINE. All is as it should be (visually). But the backup 'thinks' it is offline.

Solved it myself. This handy script will check a bunch of things and it pointed to port 8912 (used by the backup client) being the issue.

The solution to the backup problem I describe requires running the following Powershell commands (as admin) on the Server. These commands also solve an issue I had earlier in my setup where clients are connected to the Server but show as 'offline' on the Essentials Dashboard.

Powershell commands (note: replace x.x.x.x with the IP of your Server):

Run this command first:

Set-NetNatTransitionConfiguration –IPv4AddressPortPool @(“x.x.x.x,6001-6601”,“x.x.x.x,6603-8911”,"x.x.x.x,8913-47000")

Then run this:
Restart-Service winnat
