What are the key Kubernetes backup strategies for disaster recovery?
Ensuring that you can restore your Kubernetes cluster and applications to a known good state after a failure is critical. This involves understanding what a backup is, the types of backups available, and why you need to back up more than just etcd. By choosing the right methods and tools and following best practices, you can ensure that your backups are reliable and secure.
