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.

    So iSCSI is less recommended? Kubernetes documentation says no simultaneous writers allowed. Which type of storage is commonly used?
