Velero: The Open-Source Standard for Kubernetes Backup

Velero is a popular open-source tool for safely backing up and restoring Kubernetes cluster resources and persistent volumes. It provides flexibility for disaster recovery, data migration, and snapshotting entire clusters or specific applications. Velero is cloud-provider agnostic, integrating with object storage solutions like Amazon S3, Azure Blob Storage, and Google Cloud Storage.

Key Features and Use Cases for Velero

  • Cluster Backup: Backs up Kubernetes objects (deployments, services, configs) and persistent volumes.
  • Restore: Enables full cluster restore or granular application-level recovery.
  • Migration: Facilitates moving applications between clusters or cloud providers.
  • Pre/Post-hooks: Custom scripts can run before or after backup/restore operations for application quiescing.

Practical Example: Installing Velero

To get started with Velero, you typically install it using the command-line interface (CLI) or Helm. This example shows a basic CLI installation:

velero install \
  --provider aws \
  --plugins velero/velero-plugin-for-aws:v1.6.0 \
  --bucket my-velero-bucket \
  --secret-file ./credentials-velero \
  --backup-location-config region=us-east-1

This command configures Velero to use AWS S3 for storing backups. Ensure you replace placeholders with your actual bucket and region details.

Utilizing Portworx Backup

Portworx Backup is typically deployed as part of the Portworx Enterprise suite or as a standalone component. It uses custom resources within Kubernetes to define backup policies and schedules.

# Example: Basic Portworx Backup operation (simplified)
# 1. Install Portworx Backup
# 2. Create a `Backup` custom resource
apiVersion: px.purestorage.io/v1
kind: Backup
metadata:
  name: my-app-backup
  namespace: my-app-namespace
spec:
  targetVolume: my-app-pvc # PVC to back up
  targetNamespace: my-app-namespace
  backupLocation: my-s3-bucket-location
  schedule: "0 0 * * *" # Daily backup

This snippet illustrates how a backup can be declared. Actual implementation requires proper setup of backup locations and credentials.
