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.

So iSCSI is less recommended? Kubernetes documentation says no simultaneous writers allowed. Which type of storage is commonly used? – jwalker Apr 25 '20 at 12:32

It depends upon you environment (public cloud Vs. on premises).
