Hi Giordano. Unfortunately, no. At the moment, CloudCasa requires the CSI snapshot interface for PVs. CSI volume snapshot operations were beta in Kubernetes 1.17 and are stable as of Kubernetes 1.20, but as you mentioned the CSI driver for Azure volumes is still considered a preview. We hope that this will change shortly, but we are also looking at some alternative ways to address snapshots on some major cloud providers in the near-term. If you would like to contact us at firstname.lastname@example.org, we would be happy to discuss your requirements.
