Hello community,

We are running Kasten K10 v7.5.3 on OpenShift (bare metal) and encountering recurring backup job failures during the CopyVolumeData phase.

In the logs, Kasten attempts to pull images from the internal OpenShift image registry and receives multiple 401 Unauthorized responses. Example error:

GET https://image-registry.openshift-image-registry.svc:5000/openshift/token?scope=repository:<project>/<component>:pull
unexpected status code 401 Unauthorized

Only certain workloads are affected (those belonging to one project currently in a failed state by design). All other namespaces complete backups successfully.

We’ve confirmed:

The node hosting the copy-vol-data pod was ready and schedulable during retries.

Policy configuration selects only the affected namespace.

Storage backend is NFS.

Has anyone experienced Kasten backup failures caused by workloads in a failed deployment state or image registry authentication issues?

Any advice or workaround (such as excluding failed workloads from backup policies) would be appreciated.

Thanks in advance!
