Debunking the Myth: Why Your Kubernetes Apps Need Robust Backup Solutions, Part 2

Introduction

The premise that Kubernetes (K8s) applications are stateless and don’t need backups is overly simplified. Here are two key reasons why backups are still necessary:

1. Pipeline Limitations

• While tools like GitOps allow redeployment of applications, they can't help retrieve specific configuration data from past points in time (e.g., an hour, a week, or two months ago).

• Redeploying can't restore object-level data like Namespaces, Pods, or Secrets.

• Tools like ArgoCD and Influx, essential for GitOps, need backups to restore data in case of failure.

• Frequent configuration changes and "hot fixes" mean backups are necessary for accurate recovery.

2. State Dependency

• Applications often rely on databases not within the K8s cluster. During outages, achieving desired Recovery Point Objective (RPO) and Recovery Time Objective (RTO) requires considering the entire application, including its state.

• Without backups tying databases to the K8s cluster, RPO and RTO suffer, risking data loss and downtime.
