Snapshots are only supported for CSI drivers (not for in-tree or Flexvolume). To use the Kubernetes snapshots feature, ensure that a CSI Driver that implements snapshots is deployed on your cluster.

Rencana awal untuk mendukung volume menggunakan CCM adalah dengan menggunakan Flexvolume untuk mendukung penambahan volume secara _pluggable_. Namun, ada sebuah usaha lain yang diberi nama Container Storage Interface (CSI) yang sedang berlangsung untuk menggantikan Flexvolume.
