Which shared storage solutions are common for Kubernetes cluster to implement shared storage persistence for containers? NFS on NAS / iSCSI somehow? How do you backup the data on a Kubernetes with this type of storage?

It’s the same storage you use as a backend for your running virtual machines, say NFSv3/v4, iSCSI and FC. Concepts behind are very similar.
You might want to read the Docker/Kubernetes backup overview here:

It won’t be acceptable by ServerFault to recommend any particular product as its opinion-based answer, obviously.

1So iSCSI is less recommended? Kubernetes documentation says no simultaneous writers allowed. Which type of storage is commonly used?– jwalkerApr 25, 2020 at 12:32
It depends upon you environment (public cloud Vs. on premises).
