| # AwsNfsVolumeBackup Custom Resource | ||
|
|
||
| The `awsnfsvolumebackup.cloud-resources.kyma-project.io` namespaced custom resource (CR) describes the AWS EFS Filesystem backup. | ||
| While the AWS EFS Filesystem backup is created in the underlying cloud provider subscription, it needs its source AWS | ||
| EFS Filesystem instance to be available. But upon its creation, it can be used independently of the source instance. | ||
|
|
||
| For a given AWS EFS Filesystem, backups are incremental. This reduces latency on backup creation. | ||
| To learn more, read [EFS Filesystem Backup Creation](https://docs.aws.amazon.com/efs/latest/ug/awsbackup.html). | ||

| # AwsNfsBackupSchedule Custom Resource | ||
|
|
||
| The `awsnfsbackupschedule.cloud-resources.kyma-project.io` custom resource (CR) represents the user-defined schedule for creating a backup | ||
| of the `AwsNfsVolume` instances at regular intervals. The CR performs the following actions: | ||
| - Creates the backups by creating the `awsnfsvolumebackup.cloud-resources.kyma-project.io` resources at the specified interval. | ||
| - Enables you to specify days and times in the form of CRON expressions to automatically create the backups. | ||
| - Automatically deletes the backups when the backup reaches the configured maximum retention days value. | ||
| - Enables you to temporarily suspend or resume the backup creation/deletion. | ||
|

| # Backup RWX Volumes in AWS | ||
|
|
||
| This tutorial explains how to create backups for ReadWriteMany (RWX) volumes in Google Cloud Platform (AWS). | ||
|
|
||
| ## Preparation <!-- {docsify-ignore} --> | ||
|
|
||
| You have created a AwsNfsVolume. Follow [Use RWX Volumes in AWS](./01-20-aws-nfs-volume.md) to learn more. | ||
|
|
||
| [!NOTE] | ||
| All the examples below assume that the AwsNfsVolume is named `my-vol` and is in the same namespace as the AwsNfsVolumeBackup resource. | ||
|
|
||
| ## Steps <!-- {docsify-ignore} --> | ||
|
|
||
| 1. Export the namespace as an environment variable. Run: | ||
|
|
||
| ```shell | ||
| export NAMESPACE={NAMESPACE_NAME} | ||
| ``` | ||
|
|
||
| 2. Create an AwsNfsVolumeBackup resource. | ||
|
|
||
| ```shell | ||
| cat <<EOF | kubectl -n $NAMESPACE apply -f - | ||
| apiVersion: cloud-resources.kyma-project.io/v1beta1 | ||
| kind: AwsNfsVolumeBackup | ||
| metadata: | ||
| name: my-backup | ||
| spec: | ||
| source: | ||
| volume: | ||
| name: my-vol | ||
| EOF | ||
| ``` | ||
| 3. Wait for the AwsNfsVolumeBackup to be in the `Ready` state. | ||
| ```shell | ||
| kubectl -n $NAMESPACE wait --for=condition=Ready awsnfsvolumebackup/my-backup --timeout=300s | ||
| ``` | ||
| Once the AwsNfsVolumeBackup is created, you should see the following message: | ||
| ``` | ||
| awsnfsvolumebackup.cloud-resources.kyma-project.io/my-backup condition met | ||
| ``` | ||
| 4. Observe the location of the created backup. | ||
| ```shell | ||
| kubectl -n $NAMESPACE get awsnfsvolumebackup my-backup -o jsonpath='{.status.location}{"\n"}' | ||
| ``` | ||
| 5. Clean up: | ||
| * Remove the created awsnfsvolumebackup: | ||
| ```shell | ||
| kubectl delete -n $NAMESPACE awsnfsvolumebackup my-backup | ||
| ``` |

| # Create Scheduled Automatic RWX Volume Backups in Google Cloud | ||
|
|
||
| This tutorial explains how to create scheduled automatic backups for ReadWriteMany (RWX) volumes in Google Cloud (AWS). | ||
|
|
||
| ## Prerequisites <!-- {docsify-ignore} --> | ||
|
|
||
| * You have created a AwsNfsVolume. Follow [Use RWX Volumes in AWS](./01-20-aws-nfs-volume.md) to learn more. | ||
|
|
||
| > [!NOTE] | ||
| > All the examples below assume that the AwsNfsVolume is named `my-vol` and is in the same namespace as the AwsNfsBackupSchedule resource. | ||
| ## Steps <!-- {docsify-ignore} --> | ||
|
|
||
| 1. Export the namespace as an environment variable. Run: | ||
|
|
||
| ```shell | ||
| export NAMESPACE={NAMESPACE_NAME} | ||
| ``` | ||
|
|
||
| 2. Create a 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 | ||
| 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: | ||
| ``` | ||
| 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) and see that the AwsNfsVolumeBackup objects get created. | ||
| ```shell | ||
| kubectl -n $NAMESPACE get awsnfsvolumebackup -l cloud-resources.kyma-project.io/scheduleName=my-backup-schedule | ||
| ``` | ||
| 6. Clean up: | ||
| * Remove the created schedule and the backups: | ||
| ```shell | ||
| kubectl delete -n $NAMESPACE awsnfsbackupschedule my-backup-schedule | ||
| ``` |
