Step 1 - Access the Longhorn Backup Page

Navigate to the Longhorn backup page to see a comprehensive list of all available backups.

Step 2 - Recover Backups

1. Navigate to the Backup tab.

2. Select the backups you wish to recover.

   Note: If you want to recover an entire service, you must choose all the related backups.

   

3. For "Recovery Options", select "Read-Write" mode, then click "OK".

Step 3 - Bind Volumes

First, navigate to the Volumes tab.

Initially, the volume's state will be "Detached", and PV/PVC will be empty.

Create PV and PVC for the backup by selecting the backup and clicking "Create PV/PVC".

Click "OK".

The PV/PVC section of the volume will then become "Bound".

If you have multiple volumes to recover, please repeat the process for each one.

Step 4 - Deploy Services

Switch to the correct Kubernetes context:

kubectl config use-context {{k8s-context}}

Ensure the service you wish to recover is not running. You can uninstall the service using Helm:

helm uninstall {{service-name}}

Redeploy the service, and the volume will be mounted automatically.

make manually-deploy-{{service-name}} DEPLOY_ENV={{env}}
