Basic Lab Environment Configuration

vSphere 7.0

Kubernetes cluster running on vSphere VMs
Kasten K10 installed and configured for container backup
VRO v6 deployed and integrated with VBR v12

Introduction to VRO and K10 Integration

As containerized applications become increasingly critical to business operations, the need for robust disaster recovery solutions for Kubernetes environments has never been more important. Veeam Recovery Orchestrator (VRO) v6, combined with Kasten K10, provides a comprehensive solution for automated container disaster recovery that extends Veeam’s proven DR capabilities to Kubernetes workloads.

Why Combine VRO with K10?

K10 excels at Kubernetes-native backup and recovery, providing application-consistent backups, policy-based automation, and multi-cloud mobility. However, when it comes to enterprise-grade disaster recovery orchestration, compliance reporting, and automated testing, VRO brings additional capabilities that are essential for production environments:

Automated DR Orchestration: VRO can orchestrate complex multi-step recovery processes
Comprehensive Testing: Built-in DataLabs for non-disruptive DR testing
Compliance Reporting: Automated documentation generation for audit requirements
Integration with Existing Infrastructure: Seamless integration with vSphere and traditional VM workloads

Prerequisites for Integration

Before implementing VRO with K10, ensure you have the following components in place:

1. Kubernetes Cluster Requirements

        
# Verify cluster readiness
kubectl cluster-info
kubectl get nodes
kubectl get storageclass

2. K10 Installation and Configuration

Ensure K10 is properly installed with these key components:

K10 dashboard accessible
Storage profiles configured
Backup policies in place
Export location set up

3. VRO Infrastructure

VRO v6 server deployed
Integration with VBR v12 configured
Appropriate licensing for container workloads
Network connectivity between VRO and Kubernetes cluster

Architecture Overview

The integration architecture follows this pattern:

[Kubernetes Cluster] ←→ [K10] ←→ [Object Storage] ←→ [VRO] ←→ [vSphere/VBR]
      ↓                      ↓                ↓               ↓
  Container           K10 Backup        Backup           VRO Orchestration
  Workloads           Operations        Storage          and Automation

Step-by-Step Implementation

Step 1: Configure K10 Backup Export

First, ensure K10 can export backups to a location accessible by VRO:

        
        
        
    
# Example K10 export profile configuration
apiVersion: config.kio.kasten.io/v1alpha1
kind: ExportProfile
metadata:
  name: vro-storage-profile
  namespace: kasten-io
spec:
  type: ObjectStore
  objectStore:
    type: S3
    name: vro-s3-store
    region: us-east-1
    bucket: k10-backups
    accessKey: <your-access-key>
    secretKey: <your-secret-key>

Step 2: Set Up VRO Integration

Configure VRO to recognize K10 backup locations:

Add Storage Location in VRO
- Navigate to Infrastructure → Storage
- Add new object storage location pointing to K10 export bucket
- Configure credentials and connection settings
Create Container Resource Group
- Create a new resource group for container workloads
- Map Kubernetes namespaces to VRO resource groups
- Define recovery objectives (RPO/RTO)

Step 3: Define Orchestration Plan

Create a comprehensive orchestration plan for container DR:

Step 4: Configure Automated Testing

Set up regular DR testing using VRO DataLabs:

Create DataLab Environment
- Isolated network segment for testing
- Clone of production storage
- Automated environment provisioning
Define Test Scenarios
- Application functionality tests
- Data integrity verification
- Performance benchmarking
- Security validation

Step 5: Implement Monitoring and Alerting

Configure comprehensive monitoring:

        
        
        
    
# Example monitoring configuration
apiVersion: v1
kind: ConfigMap
metadata:
  name: vro-monitoring
  namespace: monitoring
data:
  prometheus.yml: |
    scrape_configs:
      - job_name: 'vro-metrics'
        static_configs:
          - targets: ['vro-server:9100']
      - job_name: 'k10-metrics'
        static_configs:
          - targets: ['k10-service:8080']

Advanced Configuration Options

Multi-Cloud Recovery Scenarios

VRO enables sophisticated multi-cloud recovery strategies:

Cross-Cloud Restore
- Restore from on-premises to cloud
- Cloud-to-cloud disaster recovery
- Hybrid cloud scenarios
Application Mobility
- Migrate applications between regions
- Blue-green deployment strategies
- A/B testing environments

Custom Script Integration

Extend VRO capabilities with custom scripts:

        
        
        
    
# Example PowerShell script for application verification
param(
    [string]$Namespace,
    [string]$AppName
)

# Verify pod status
$pods = kubectl get pods -n $Namespace -l app=$AppName -o json
$runningPods = ($pods.items | Where-Object { $_.status.phase -eq "Running" }).Count

if ($runningPods -eq 0) {
    Write-Error "No running pods found for application $AppName"
    exit 1
}

# Verify service connectivity
$service = kubectl get svc $AppName -n $Namespace -o json
if (-not $service) {
    Write-Error "Service not found for application $AppName"
    exit 1
}

Write-Host "Application $AppName verification successful"

Best Practices and Recommendations

1. Backup Strategy

Frequency: Align K10 backup policies with business RPO requirements
Retention: Implement appropriate retention policies for compliance
Testing: Regular validation of backup integrity
