Backup and Restore

Learn how to backup and restore your KubeZero platform and applications.

Overview​

KubeZero provides comprehensive backup and restore capabilities for both platform components and application data.

Backup Strategy​

Implement a comprehensive backup strategy:

  • Platform Configuration: GitOps repository backups
  • Application Data: Persistent volume backups
  • Cluster State: etcd backups
  • Secrets: Encrypted secret backups

Automated Backups​

Configure automated backup schedules:

# Backup configuration
backup:
  enabled: true
  schedule: "0 2 * * *"  # Daily at 2 AM
  retention: 30d
  storage:
    provider: s3
    bucket: kubezero-backups
    region: us-west-2

Platform Backup​

GitOps Repository​

Your platform configuration is version controlled:

# Backup GitOps repository
git clone https://github.com/your-org/kubezero-config.git
cd kubezero-config
git push --mirror https://backup-location/kubezero-config.git

Cluster State​

Backup cluster state and configurations:

# Backup cluster resources
kubezero backup cluster --output cluster-backup.tar.gz

# Backup specific namespaces
kubezero backup namespace --namespace production

Application Data Backup​

Persistent Volumes​

Backup persistent volume data:

# Volume snapshot configuration
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
metadata:
  name: database-snapshot
spec:
  source:
    persistentVolumeClaimName: database-pvc

Database Backups​

Configure database-specific backups:

# PostgreSQL backup example
apiVersion: batch/v1
kind: CronJob
metadata:
  name: postgres-backup
spec:
  schedule: "0 1 * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: postgres-backup
            image: postgres:14
            command:
            - pg_dump
            - -h
            - postgres-service
            - -U
            - postgres
            - -d
            - myapp

Disaster Recovery​

Plan for disaster recovery scenarios:

Recovery Time Objective (RTO)​

Target recovery times:

  • Platform restoration: < 2 hours
  • Application restoration: < 1 hour
  • Data restoration: < 30 minutes

Recovery Point Objective (RPO)​

Acceptable data loss:

  • Configuration: 0 (GitOps)
  • Application data: < 1 hour
  • Logs: < 15 minutes

Restore Procedures​

Platform Restore​

Restore KubeZero platform:

# Restore from backup
kubezero restore cluster --input cluster-backup.tar.gz

# Verify platform health
kubezero status --all

Application Restore​

Restore application data:

# Restore persistent volumes
kubectl apply -f volume-snapshots.yaml

# Restore application manifests
kubezero app deploy --from-backup app-backup.yaml

Testing Backups​

Regularly test backup and restore procedures:

  1. Automated Testing: Run monthly restore tests
  2. Documentation: Keep procedures updated
  3. Training: Train team on restore procedures
  4. Validation: Verify data integrity

Backup Security​

Secure your backups:

  • Encryption: Encrypt backups at rest and in transit
  • Access Control: Limit backup access
  • Audit: Log backup and restore activities
  • Retention: Follow data retention policies

Monitoring​

Monitor backup operations:

  • Backup success/failure rates
  • Backup completion times
  • Storage utilization
  • Restore test results
