I noticed that this project supports VolumeSnapshot. I would also like to be able to restore from the snapshots taken, i.e. creating a PVC from a snapshot.

example:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-restore
spec:
  dataSource:
    name: my-snapshot
    kind: VolumeSnapshot
    apiGroup: snapshot.storage.k8s.io
  storageClassName: lvm
  accessModes:
    - ReadWriteOnce

My goal is to be able to use a backup tool like Kasten K10 to backup my PVCs to s3. For this it needs snapshot and restore functionality.

I have very similar use case like described above.

Being able to make a snapshot is very useful but you also need to be able to use it)))

Thanks in advance

And will be very useful if you can give ETA

Is there any going on update？

Any chance for this to be implemented? I expected lvm-localpv supports backups with velero but seems not vmware-tanzu/velero#7044

Needs scoping in roadmap. Bringing to notice.

As per the discussion, this will be scoped for the next release i.e. OpenEBS v4.3

A lvm-localpv user is running into this issue as well with Backsnap (a backup operator which uses VolumeSnapshots for point-in-time incremental off-site backups). They also found that the lvm-localpv operator can fulfill VolumeSnapshots, but keeps the status.restoreSize set to 0. While this is being implemented for OpenEBS v4.3, could you consider taking into account a correct value for VolumeSnapshot status.restoreSize as well, so that restore PVCs can be created with the correct size to contain a single full restore?

Until this feature is functional, a user has validated manual steps and documented the same here: #175 (comment)
