I'm not stating anything is or isn't true. I'm only stating that based on a a quick review it seems Overland has been a client of ESG since at least 2004.
I see nothing wrong with SnapCLOUD. I just see it as another me-too product, effectively re-selling Azure storage into their (shrinking, it seems, based on revenue) customer base. So you can add some cloud storage into your Overland NAS environment. Big deal.
