CSI Volume Snapshots
Avisi Cloud Kubernetes supports Volume Snapshots. With Volume Snapshots, you are able to create a snapshot of a Persistent Volume within your Kubernetes cluster using familiar APIs.
acloud-toolkit
We provide tooling to easily create volume snapshots. Check out our acloud-toolkit.
Snapshot controller
Avisi Cloud by default installs the snapshot controller within each cluster. We also provide a volumesnapshotclass to enable CSI Snapshot creation. The exception here is within Bring Your Own Node clusters, where we are unable to determine which CSI driver needs to be running.
