Kubernetes has been the bedrock on which most modern-day cloud-native apps have been built- thus providing organizations with a highly efficient way of deploying and managing their workloads. The self-healing nature, automatic scaling, and high availability features of Kubernetes give a false sense that applications are inherently resilient against failures.<\/span><\/p>\n

However, high availability is not equivalent to disaster recovery.<\/span><\/p>\n

While Kubernetes is capable of recovering from node failures and restarting unhealthy containers, it does not have the ability to automatically recover any deleted data or rebuild any application in case of any ransomware attack or infrastructure breakdown. Failure to implement a backup and disaster recovery strategy could result in extended downtime, data loss, and ultimately business disruption.<\/span><\/p>\n

Therefore, Kubernetes backup and disaster recovery becomes a must-have capability for businesses.<\/span><\/p>\n

Why Kubernetes Backup is More Challenging<\/b><\/h4>\n

While regular applications have simple structures, Kubernetes applications are composed of several connected components. Restoration of an application cannot be done through restoration of its database since the whole environment must be restored.<\/span><\/p>\n

The recovery solution should ensure that both the application and cluster states are protected.<\/span><\/p>\n

    \n
  1. Persistent Data<\/span><\/li>\n<\/ol>\n

    Persistent volumes store valuable business data like databases, customer files, transactional logs, and applications themselves. Failure of such volumes usually means loss of the most valuable asset of the application.<\/span><\/p>\n

      \n
    1. Kubernetes Resources<\/span><\/li>\n<\/ol>\n

      Deployments, StatefulSets, Services, Namespaces, and Jobs describe how applications are deployed and managed. Such resources are equally important as the actual data during the recovery process.<\/span><\/p>\n

        \n
      1. Configurations and Secrets<\/span><\/li>\n<\/ol>\n

        ConfigMaps and Secrets are needed by applications to be configured properly, to connect with APIs, access certificates, and connect to databases.<\/span><\/p>\n

          \n
        1. Cluster Configuration<\/span><\/li>\n<\/ol>\n

          Cluster metadata such as RBAC policies, storage classes, network policies, and CRDs play an important part in Kubernetes environments recovery.<\/span><\/p>\n

          Common Disaster Scenarios<\/b><\/h4>\n

          Disaster recovery should prepare for a variety of practical situations such as:<\/span><\/p>\n
