So, for once I’m writing something about security more than virtualization, because this news about SSL totally deserves an article. TLS is hard……

An example of Veeam Scale-Out Backup Repository mixing whitebox servers
Since Veeam announced the Scale-Out Backup Repository technology coming in Veeam Backup & Replication v9, I’ve been asked already multiple times to give some practical examples on how to leverage it. Let’s see together one interesting way to leverage the “performance” policy available in Scale-Out Backup Repository.
