Creating Scheduled Automatic NFS Volume Backups in Amazon Web Services ​

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 Amazon Web Services (AWS).

Prerequisites ​

NOTE

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

Steps ​

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

    shell
    export NAMESPACE={NAMESPACE_NAME}

  2. Create an AwsNfsBackupSchedule resource.

    shell
    cat <<EOF | kubectl -n $NAMESPACE apply -f -
apiVersion: cloud-resources.kyma-project.io/v1beta1
kind: AwsNfsBackupSchedule
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 AwsNfsVolumeBackup to be in the Active state.

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

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

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

  4. Observe the nextRunTimes for creating the backups.

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

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

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

Next Steps ​

To clean up, follow these steps:

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

    shell
    export NAMESPACE={NAMESPACE_NAME}

  2. Remove the created schedule and the backups:

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