velero can use CSI Snapshot for backup according to this https://velero.io/blog/csi-integration/
can zfs-localpv use this feature without needing extral plugin?
To my understanding, nfs-localpv is already support CSI Snapshot, it should be a simple work, right?

Anything else you would like to add:

Environment:

• ZFS-LocalPV version
• Kubernetes version (use kubectl version):
• Kubernetes installer & version:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):

@liyimeng yes, CSI Snapshot can be used for backup. We can use the velero CSI plugin for backing up the data. Just a note here, the data will be backed up locally only as it will be backed up as a zfs snapshot.

I'm interested in this question. I'd like to be able to take backups and volume snapshots of Kubevirt VMs and have them uploaded to S3

According to this vmware-tanzu/velero#3544 it should be supported in Velero, but unsure if zfs-localpv supports it on the backend.

I tried using the CSI snapshot with https://github.com/vmware-tanzu/velero-plugin-for-csi and while the volume snapshot did succeed, I couldn't get it to upload to S3 (velero backup would get stuck in WaitingForPluginOperations phase).

I've ended up using https://github.com/openebs/velero-plugin instead of velero-plugin-for-csi and that does what I need, however I'm concerned that velero-plugin may be deprecated - see: #511

@ianb-mp https://github.com/openebs/velero-plugin will not be deprecated. It will be considered for development and enhancements.
