Cluster Backup Overview

Based on Velero, Cluster Backup provides a unified solution for backing up, restoring, and migrating applications and data in Kubernetes clusters. It supports backup and restoration of both resource objects (such as Deployments, Services, and ConfigMaps) and persistent volume data (PVs and PVCs), enabling disaster recovery and cross-cluster migration.

Cluster Backup provides efficient, reliable backup and restoration for diverse scenarios:

  • Comprehensive data protection: Cloud-native backups safeguard cluster applications and data, ensuring service continuity and data security.
  • Flexible backup policies: Scheduled backups and customizable resource scopes adapt to diverse service requirements.
  • Cross-cluster operations: Backup and restoration across clusters enable flexible resource migration and disaster recovery.

How It Works

In Huawei Cloud CCE, Cluster Backup provides two types of resource backup:

  • Cluster resource backup: Velero backs up application resources (such as YAML manifests for Deployments, Services, and ConfigMaps) and stores the backup files securely in a designated OBS bucket.
  • PV data backup: EVS snapshots back up EVS storage volumes.

Notes and Constraints

Cluster Backup supports data backup and restoration for EVS storage volumes only.

Billing

Cluster Backup itself is free of charge. However, associated resources incur costs:

  • Backup repositories require an OBS bucket, which generates OBS fees. For details, see OBS Billing Overview.
  • PV backup automatically creates EVS snapshots, which incur snapshot fees. For details, see Billing for EVS Snapshots.

Enabling Cluster Backup

Cluster Backup is enabled by default if Velero is installed in the cluster.

  1. Log in to the CCE console and click the cluster name to access the cluster console.
  2. In the navigation pane, choose Cluster Backup. Click Enable and configure Velero installation parameters. For details, see Installing the Add-on.
  3. Click Install. Once the add-on is installed, Cluster Backup is available for use.
