Velero: Kubernetes Backup, Recovery, and Migration

by Shriira Press

Velero is an open-source, CNCF tool that protects what lives inside a Kubernetes cluster: the API objects that describe your applications and the persistent volumes that hold their data. When a cluster is lost, a namespace is deleted by accident, or an upgrade goes wrong, Velero is what lets you recover — and the same portable backup also moves workloads between clusters. This book starts with the problem Velero solves, then works through its architecture as Kubernetes controllers and custom resources, how cluster objects and volume data are captured through cloud snapshots, file-system backup, and CSI data movement, and finally restores, scheduling, retention, hooks, and running Velero well in production.
