Controlplane backup12/3/2023 ![]() ![]() The problem with this approach is it simply doesn’t scale. If your environment is still small, it may be possible to write scripts that use Kubernetes APIs to backup or snapshot the pods, services, ConfigMaps, data stores, and secrets associated with each application. Because Kubernetes backup and recovery is essential to the continued success of your business, here are seven common mistakes you will want to avoid at all costs: Mistake 1: Managing backups with manually written scripts Operators and developers make errors, even the most robust hardware and software can crash, and with cyber crime reaching new heights, your backups are often the last line of defense against malfeasance. A full Kubernetes cluster backup must include: all Kubernetes control plane data stored in /etcd, all namespaces, and all PVs. To enable a successful restore, a Kubernetes application backup has to capture all of this information. Instances of containers come and go according to load or other factors, and data is written to separate persistent volumes or PVs, which can be created dynamically. A single application in production may consist of hundreds of components, including containers/pods, ConfigMaps, certificates, secrets, and volumes. Kubernetes environments are far more dynamic. Why is Backing Up Kubernetes Different?īacking up an application running on Kubernetes is not like backing up an app running in a virtual machine. This blog explores Kubernetes backup risks and Kubernetes backup best practices by examining seven common Kubernetes backup and recovery mistakes. The problem with backing up Kubernetes is that it is easy to get it wrong, making it difficult (or impossible) to restore a cluster or application to a functional state without a heroic effort. Migrate a cluster from one environment to another (on-prem to cloud or vice versa).Recover a specific application (for instance after data corruption).Recover entire clusters in case of disaster.There are several use cases that your Kubernetes backup and recovery strategy should satisfy: You need an effective and appropriate backup strategy- in addition to whatever built-in resiliency and data protection features your applications may have. Implementing Kubernetes backup is critical to protect your applications in the event of an accident, system failure, or deliberate attack. As enterprises move Kubernetes into production and increase the number of Kubernetes clusters and applications in use, they need to deliver the same “enterprise-level” services as for other production applications.
