I am planning a new veeam setup for the company, and I have looked into the Scale-Out Repository solution. But the problem is that I only having Enterprise license.

So I just want to ask out there, can I create unlimit Scale-Out Repository groups - with ONLY 3 extends each? (example, 5 x Scale-Out Repository, with 2 extends/servers in each group).
Or is the "3" limit overall for everything?
And last, is there anybody out there that have found another alternative solution? Linux/Windows - whatever?
