Cloud backups don't suit every scenario though. The video editing studio here got a new 40TB storage device and filled it in months, and are talking about going bigger next time. They are struggling on rural Australian internet with a service that varies between 10 and 2mbit depending on the weather, often with high degrees of packet loss.

Multiple "experts" have walked through the door and demanded they move all backups to various cloud based services. Trying to tell people that some great solutions aren't always great for every scenario is like talking to a wall.

You should back up your critical files somewhere else than in a place where someone can wipe them, preferably off-line.

Out of band.

You don't want crypto-ransomware able to get to your keys to the backups.

Anybody have recommendations for decent providers of such backup services?
