Delete the NetBackup Kubernetes operator
You can delete a NetBackup Kubernetes operator deployment from a cluster.
helm uninstall <plugin-name> -n <Netbackup Kubernetes Operator Namespace>
Note:
By uninstalling the plugin, the NetBackup Kubernetes operator PVC is also deleted which has metadata elated to snapshot based backups.
NetBackup Kubernetes operator deletion can result loss of metadata volume, which also hosts the snapshot metadata. If any snapshots are already performed, then restore from snapshot copy operation fails in the absence of metadata.
In NetBackup 9.1, you must first delete the older snapshots manually then delete the associated Velero snapshots.
In NetBackup 10.0, you cannot perform expiration of Velero managed snapshots which were created using NetBackup 9.1. When the backup images are expired in NetBackup, the catalog is automatically cleared. But you must delete the snapshot on Kubernetes server manually.
For more details on manual image expiration operation, see https://support.cohesity.com/s/.
Note:
Without expiring the snapshots or without deleting persistent volume snapshots, if Kubernetes Operator is uninstalled then orphan volume snapshot will be lying around Kubernetes Cluster.
