Openshift backup using Netbackup and the Netapp trident plugin

Hello

I am useing Netbackup 10.0.0.1 at the moment. I have configured the kubernetes backup (using the webui) to backup  our Openshift cluster. Everything is working fine except the backup of the PVCs. In the backend of openshift we use the Netapp trident plugin. I get the following error in OC: "Failed to find suitable volumesnapshotclass for pvc". I followed the quick start guide .

OpenShift version 4.8.36

Netbackup Primary Server: Windows Server 2019 NBU: 10.0.0.1

Netbackup Media Server: RedHat 7.9 NBU: 10.0.0.1

Has anyone configured OC backup using the trident plugin and Netbackup?

thanks

    Hi,

    You need to label storageclass and volume snapshot class so that Netbackup Kubernetes Operator can take proper action to create snapshots.

    Run "oc get sc" and "oc get volumesnapshotclass" first.

    Then follow the sample below.

    oc label sc ocs-storagecluster-ceph-rbd netbackup.veritas.com/default-csi-storage-class=true
    oc label volumesnapshotclass ocs-storagecluster-rbdplugin-snapclass netbackup.veritas.com/default-csi-volume-snapshot-class=true

      Hello

      thanks. I already did that. I found out that I used the wrong driver in the VSC. Snapshots are working now but the Backup from Snapshot operation fails. I get the following error:

       It looks like the communication to the media server is ok.
