Configuring Backups

The snapshots feature is a backup and restore option that lets you define a manifest for creating backups and restoring previous backups. The backups include all of the annotated volumes in the archive. For more information, see About Backup and Restore.

note

If you are using multiple applications, repeat this procedure for each application. Every application must have its own Backup resource to be included in a full backup.

To configure backups:

Enable backups:
1. Add a Backup resource (kind: Backup) using apiVersion: velero.io/v1 to the application manifest files. The following minimal YAML example enables backups in the application. For more information about Backup resource options, see Velero Backup Custom Resource.
  
  Example:
```
apiVersion: velero.io/v1
kind: Backup
metadata:
  name: backup
spec: {}
```
2. (Optional) Configure the resources annotation in the manifest so that it can be dynamically enabled based on a license field or a config option. For more information, see Including Optional and Conditional Resources.

Configure backups for each volume that requires a backup. By default, no volumes are included in the backup. If any pods mount a volume that should be backed up, you must configure the backup with an annotation listing the specific volumes to include in the backup.

The annotation name is backup.velero.io/backup-volumes and the value is a comma separated list of volumes to include in the backup.

For example, in the following Deployment manifest file, pvc-volume is the only volume that is backed up. The scratch volume is not included in the backup because it is not listed in annotation on the pod specification.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sample
  labels:
    app: foo
spec:
  replicas: 1
  selector:
    matchLabels:
      app: foo
  template:
    metadata:
      labels:
        app: foo
      annotations:
        backup.velero.io/backup-volumes: pvc-volume
    spec:
      containers:
      - image: k8s.gcr.io/test-webserver
        name: test-webserver
        volumeMounts:
        - name: pvc-volume
          mountPath: /volume-1
        - name: scratch
          mountPath: /volume-2
      volumes:
      - name: pvc-volume
        persistentVolumeClaim:
          claimName: test-volume-claim
      - name: scratch
        emptyDir: {}

(Optional) Configure manifest exclusions. By default, Velero also includes backups of all of the Kubernetes objects in the namespace.

To exclude any manifest file, add a velero.io/exclude-from-backup=true label to the manifest to be excluded. The following example shows the Secret manifest file with the velero.io/exclude-from-backup label:
```
apiVersion: apps/v1
kind: Secret
metadata:
  name: sample
  labels:
    velero.io/exclude-from-backup: "true"
stringData:
  uri: Secret To Not Include
```
(Optional) If you are distributing your application with Replicated kURL, Replicated recommends that you include the kURL Velero add-on so that customers do not have to manually install Velero on their cluster. For more information about distributing with kURL, see Creating a kURL installer.
