Doesn't BitTorrent Sync allow two ways sync?
The app is available onboth ReadyNAS and Synology.

But, two sync is NOT a backup! If you delete a file, or overwrite a file on one side, you sync it to the other side. Imho, it's actually more dangerous to sync two locations (and having no backup) than having no "backup" at all. Because if one side gets compromised (CryptoLocker), deleted or corrupt (in some certain ways), the same will happen to the other side, so you increase the chances of it happening.
Regardless of that, I believe you should always have an external true backup ;)

It's not available on his duo v2s. Though I suspect it could be manually installed with ssh.

I agree, the effect of 2-way sync is simply to increase the attack surface from one device to two devices.
