How to setting up SSR 2013 on W2008R2 SQL Cluster

Hello every body,

This is my first post, hope be clear to explain my doubt:

Scenario:

- 2 Win-2008R2 Servers

- SQL 2008 Cluster (just one instance)

I'm using SSR-2013 to backup Physical Servers.

Is there any best practice to install it? On Nonde1 or Node2 or Both?

Thank you in advance.

Regards
