Kubernetes has revolutionized application deployment by making workloads portable, scalable, and resilient. But this flexibility brings new risks—data loss from failed pods, accidental deletions, or cluster outages can happen fast in such dynamic environments. Traditional backup methods often miss critical Kubernetes resources or fail to restore entire applications as expected. That’s why mastering Kubernetes native backup is now a must-have skill for every operations administrator who wants to avoid downtime and meet compliance requirements.
What is Kubernetes Native Backup?
Kubernetes native backup means using tools designed specifically for the Kubernetes platform itself—not generic VM or file-level solutions retrofitted for containers. These tools interact directly with Kubernetes APIs to capture everything: deployments, services, secrets, persistent volumes—even custom resources unique to your environment.
Unlike legacy approaches that might only back up disk data or static files, native solutions understand how your cluster works as a whole system. They let you back up both configuration (like YAML manifests) and stateful data together so you can recover complete applications quickly after an incident.
Why Use Native Backup Methods?
Native backup methods are purpose-built for the fast-changing nature of container orchestration platforms like Kubernetes. They automatically discover new resources as they're created—no need to update scripts every time your team deploys something new.
These tools also support advanced features like namespace-level backups or label selectors so you can target exactly what matters most in your environment. You get tighter integration with security controls through Role-Based Access Control (RBAC), ensuring only authorized users manage backups.
From an operational perspective, native backups help reduce manual work by supporting automation pipelines common in DevOps workflows—and they fit right into CI/CD processes without extra glue code.
Method 1: Using Velero for Native Backup
Velero is one of the most widely adopted open-source tools for Kubernetes native backup today. It lets you protect both cluster resources (like deployments/services) and persistent volumes across cloud providers or on-premises clusters—all through simple commands that use standard Kubernetes APIs.
Before starting with Velero:
Make sure you have kubectl configured with admin access
Your cluster should have internet connectivity if using cloud storage
Set up credentials for your chosen object storage backend
Installing Velero
To install Velero on Linux using AWS S3 as an example:
velero install \
--provider aws \
--plugins velero/velero-plugin-for-aws:v1.8.0 \
--bucket <YOUR_BUCKET> \
--backup-location-config region=<YOUR_REGION> \
--snapshot-location-config region=<YOUR_REGION> \
--secret-file <PATH_TO_CREDENTIALS>
Replace <YOUR_BUCKET>, <YOUR_REGION>, <PATH_TO_CREDENTIALS> with real values from your environment setup guide.
After running this command:
You should see confirmation messages indicating successful deployment of Velero components (Deployment, ServiceAccount, etc.) in the velero namespace
Check pod status using kubectl get pods -n velero
Creating Backups
To create a full-cluster backup:
velero backup create my-backup
This command triggers a snapshot of all supported resources—including persistent volume claims if your storage class allows it.
Want just one namespace? Try:
velero backup create my-backup --include-namespaces my-namespace
Or use labels:
velero backup create my-backup --selector app=my-app
You’ll see output confirming the job was created; check progress via:
velero backup describe my-backup --details
Scheduling Automatic Backups
Automate regular protection by scheduling jobs:
velero schedule create daily-backup --schedule "0 2 * * *"
This sets up daily runs at 2 AM UTC—adjust timing as needed per local policy.
Restoring from Backups
When disaster strikes—or during testing—you can restore everything backed up earlier:
velero restore create --from-backup my-backup
Restoration recreates all captured objects; monitor progress via kubectl get restores -n velero.
Method 2: Using Stash by AppsCode for Native Backup
Stash by AppsCode takes a different approach—it uses Custom Resource Definitions (CRDs) so all configuration lives inside your cluster alongside other workloads. This makes it easy to automate protection through GitOps workflows while keeping everything declarative and version-controlled.
Before deploying Stash:
Installing Stash Operator Pattern Explained
Stash runs as an operator—a controller watching custom resources you define (like Repository or BackupConfiguration). Operators extend core Kubernetes functionality without modifying upstream code; they react automatically when you apply new CRDs describing desired state changes such as initiating a scheduled backup job.
Install Stash operator into the kube-system namespace:
helm repo add appscode https://charts.appscode.com/stable/
helm repo update
helm install stash appscode/stash --namespace kube-system
Check readiness via:
kubectl get pods -n kube-system | grep stash
Configuring Repositories & Scheduling Backups
First define where backups go—a Repository CRD pointing at S3-compatible storage:
apiVersion: stash.appscode.com/v1alpha1
kind: Repository
metadata:
name: s3-repo
namespace: demo # make sure this namespace exists!
spec:
backend:
s3:
endpoint: s3.amazonaws.com
bucket: <YOUR_BUCKET>
region: <YOUR_REGION>
prefix: backups
storageSecretName: s3-secret # secret must exist in 'demo'
Apply this manifest after creating any required secrets (kubectl apply -f repository.yaml).
Next set up automated schedules using BackupConfiguration CRDs:
apiVersion: stash.appscode.com/v1beta1
kind: BackupConfiguration
metadata:
name: cluster-resource-backup
namespace: demo
spec:
repository:
name: s3-repo
schedule: "0 2 * * *" # daily at 2AM UTC
task:
name: kubedump-backup-0.1.0
retentionPolicy:
name: keep-last-5
keepLast: 5
prune: true
Each time this runs it creates a new BackupSession object tracking results—check them via kubectl get backupsessions -n demo.
To restore data later define RestoreSession CRDs referencing specific sessions/backups previously created.

Kubernetes Native Backup FAQs
Q1: Can I verify that my scheduled kubernetes native backups actually contain all required resources?
Yes—run test restores regularly into isolated namespaces/clusters then compare restored objects against production manifests/resources before relying on them in disaster scenarios.
Q2: How do kubernetes native backups affect node performance during peak business hours?
Backups may temporarily increase CPU/disk/network usage; schedule large jobs outside peak times where possible—or throttle concurrency settings within tool configs if available—to minimize user impact.
Q3: What's the best way to monitor ongoing kubernetes native backup health?
Integrate Prometheus-compatible metrics exposed by most operators/tools into Grafana dashboards then set alerts based on failure rates/job durations/completion status indicators visible there.
