Kubernetes is a PaaS that permits you to run the workload as a container. Frequently, it needs to withstand the workload of their country.
K8S supports a variety of native storage driver, and the option to use an external driver there too. When choosing a storage driver, you need to consider performance, access mode volume, availability, and scalability. You can know more about top storage solutions for Kubernetes from various online stores.
Kubernetes Volume Access Mode
Kubernetes supports three access modes Volume: read-only, Read Write Only and Read Write Many. Be careful when selecting a volume driver, because some may not support all three modes.
Many drivers do not support Read Write Many. However, if the mode Read Write Many is important to you, the driver is the most commonly used is NFS.

Persistent Volume Backup and Restore
Once configured for Kubernetes storage, you need to study Kubernetes backup and restore protocols. There are some tools out there to support this, and some drivers own storage backup system implemented. Here are some sources dealing with possible solutions:
