Knowledge Tutorial

Velero is a cloud-native tool designed to backup and restore Kubernetes cluster resources and persistent volumes. It enables disaster recovery, data migration, and the replication of production clusters to development environments. A key feature is the support for restore hooks, allowing users to execute custom actions (via InitContainers or Exec commands) during the restoration process.
