Creating Scheduled Automatic NFS Volume Backups in Google Cloud ​

WARNING

This is a beta feature available only per request for SAP-internal teams.

WARNING

Long-running or frequent schedules can create too many backups and may result in cloud provider quota issues. For more information on how to avoid such issues, see Scheduling Best Practices.

This tutorial explains how to create scheduled automatic backups for Network File System (NFS) volumes in Google Cloud.

Prerequisites ​

NOTE

All the examples below assume that the GcpNfsVolume is named my-vol and is in the same namespace as the GcpNfsBackupSchedule resource.

Steps ​

  1. Export the namespace as an environment variable. Run:

    shell
    export NAMESPACE={NAMESPACE_NAME}

  2. Create a GcpNfsBackupSchedule resource.

    shell
    cat <<EOF | kubectl -n $NAMESPACE apply -f -
apiVersion: cloud-resources.kyma-project.io/v1beta1
kind: GcpNfsBackupSchedule
metadata:
   name: my-backup-schedule
spec:
   nfsVolumeRef:
     name: my-vol
   schedule: "0 * * * *"
   prefix: my-hourly-backup
   maxRetentionDays: 30
   maxReadyBackups: 100
   deleteCascade: true
EOF

  3. Wait for the GcpNfsVolumeBackup to be in the Active state.

    shell
    kubectl -n $NAMESPACE wait --for=jsonpath='{.status.state}'=Active gcpnfsbackupschedule/my-backup-schedule --timeout=300s

    Once the GcpNfsVolumeBackup is created, you should see the following message:

    console
    gcpnfsbackupschedule.cloud-resources.kyma-project.io/my-backup-schedule condition met

  4. Observe the nextRunTimes for creating the backups.

    shell
    kubectl -n $NAMESPACE get gcpnfsbackupschedule my-backup-schedule -o jsonpath='{.status.nextRunTimes}{"\n"}'

  5. Wait till the time specified in the nextRunTimes (in the previous step) and see that the GcpNfsVolumeBackup objects get created.

    shell
    kubectl -n $NAMESPACE get gcpnfsvolumebackup -l cloud-resources.kyma-project.io/scheduleName=my-backup-schedule

Next Steps ​

To clean up, remove the created schedule and the backups:

shell
kubectl delete -n $NAMESPACE gcpnfsbackupschedule my-backup-schedule
