Introduction

For more information about how to install migrate-controller, see Install the application backup component.

Velero is a cloud-native tool that can be used to back up, restore, and migrate applications in Kubernetes clusters. Velero is written in Go. Velero ensures data security when you use it to back up, restore, and migrate applications and persistent volumes (PVs) in ACK clusters. For more information about the source code of the Velero project, see Velero. For more information about the source code of the Velero plug-in for Alibaba Cloud, see velero-plugin.
Note Velero requires Kubernetes versions later than V1.10.
