Restoring NFS Volume Backups in Google Cloud

WARNING

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

This tutorial explains how to initiate a restore operation for the Network File System (NFS) volumes in Google Cloud. You can do it either using an existiong filestore or a new one.

Prerequisites

• You have the Cloud Manager module added.
• You have created a GcpNfsVolume. See Use Network File System in Google Cloud.
• You have created a GcpNfsVolumeBackup. See Back Up Network File System Volumes in Google Cloud.

NOTE

All the examples below assume that the GcpNfsVolume is named my-vol, the GcpNfsVolumeBackup is named my-backup and both are in the same namespace as the GcpNfsVolumeRestore resource.

Use an Existing Filestore

Steps

1. Export the namespace as an environment variable.

   export NAMESPACE={NAMESPACE_NAME}

2. Create an GcpNfsVolumeRestore resource.

   cat <<EOF | kubectl -n $NAMESPACE apply -f -
   apiVersion: cloud-resources.kyma-project.io/v1beta1
   kind: GcpNfsVolumeRestore
   metadata:
     name: my-restore
   spec:
     source:
       backup:
         name: my-backup
         namespace: $NAMESPACE
     destination:
       volume:
         name: my-vol
         namespace: $NAMESPACE
   EOF

3. Wait for the GcpNfsVolumeRestore to be in the Done state and have the Ready condition.

   kubectl -n $NAMESPACE wait --for=condition=Ready gcpnfsvolumerestore/my-restore --timeout=600s

   Once the GcpNfsVolumeRestore is completed, you should see the following message:

   gcpnfsvolumerestore.cloud-resources.kyma-project.io/my-restore condition met

Next Steps

To clean up, remove the created GcpNfsVolumeRestore:

kubectl delete -n $NAMESPACE gcpnfsvolumerestore my-restore

Create a New Filestore

Steps

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

   export NAMESPACE={NAMESPACE_NAME}

2. Create a new GcpNfsVolume resource with sourceBackup referring to the existing backup.

   cat <<EOF | kubectl -n $NAMESPACE apply -f -
   apiVersion: cloud-resources.kyma-project.io/v1beta1
   kind: GcpNfsVolume
   metadata:
     name: my-vol2
   spec:
     location: us-west1-a
     capacityGb: 1024
     sourceBackup:
       name: my-backup
       namespace: $NAMESPACE
   EOF

3. Wait for the GcpNfsVolume to be in the Ready state.

   kubectl -n $NAMESPACE wait --for=condition=Ready gcpnfsvolume/my-vol2 --timeout=600s

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

   gcpnfsvolume.cloud-resources.kyma-project.io/my-vol2 condition met

Next Steps

To clean up, remove the created GcpNfsVolume:

kubectl delete -n $NAMESPACE gcpnfsvolume my-vol2
