Recommendations of NetBackup deployment on AKS

Note the following recommendations:

  • Use Azure Premium storage for data volume in media server CR.

  • Use Azure Standard storage for log volume in media server CR.

  • For primary server catalog volume, use Azure premium files as storage type and for media server volumes, use managed-disk as storage type.

  • Do not delete the disk linked to PV used in primary server and media server CR deployment. This may lead to data loss.

  • Ensure that in one cluster, only one NetBackup operator instance is running.

  • Do not edit any Kubernetes resource created as part of primary server and media server custom resource. Update is supported through custom resource update only.

  • Detailed primary server custom resource deployment and media server custom resource deployment logs are retrieved from NetBackup operator pod logs using the kubectl logs <netbackup-operator-pod-name> -c netbackup-operator -n <netbackup operator-namespace> command .

  • Deploy primary server custom resource and media server custom resource in same namespace.

  • Ensure that you follow the symbolic link and edit the actual persisted version of the file, if you want to edit a file having a symbolic link in the primary server or media server.

  • Do not skip the Config-Checker utility execution during NetBackup upgrade or data migration.

  • Specify different block storage based volume to obtain good performance when the nbdeployutil utility does not perform well on Azure premium files based volumes.
