Hi @straight-nest-8449, Could you help to create a GH issue to describe your situation and attach the support bundle for confirmation? I thought we might be missing some cases here, but need to confirm that with your support bundle. Thanks!

@straight-nest-8449 did you follow these steps? https://github.com/harvester/harvester/issues/2405#issuecomment-1557428207 Mostly step 4 and 5?

Thanks@happy-cat-90847 for the reminder. @straight-nest-8449, could you verify again with the above steps to set up rook and try VM backup again?

@happy-cat-90847 @salmon-city-57654 The snapshot class is configured. Here's my CSI driver config:

{
  "<http://driver.longhorn.io|driver.longhorn.io>": {
    "volumeSnapshotClassName": "longhorn-snapshot",
    "backupVolumeSnapshotClassName": "longhorn"
  },
  "<http://rook-ceph.rbd.csi.ceph.com|rook-ceph.rbd.csi.ceph.com>": {
    "volumeSnapshotClassName": "ceph-block",
    "backupVolumeSnapshotClassName": "ceph-block"
  }
}

And the associated snapshot class:
