Container Service for Kubernetes:migrate-controller

Last Updated:Feb 02, 2024

The migrate-controller component is developed based on open source Velero. migrate-controller is deeply integrated with the snapshot technologies and Cloud Backup service of Alibaba Cloud. You can use migrate-controller to back up, restore, and migrate data and application templates. This topic introduces migrate-controller and describes the release notes for migrate-controller.

Introduction

For more information about how to install migrate-controller, see Install migrate-controller and grant permissions.

You can use migrate-controller to back up applications and persistent volumes (PVs) in your Kubernetes clusters. A variety of policies are supported to filter the applications that you want to back up. For example, you can back up applications based on namespaces, labels, and resource types. migrate-controller allows you to create disk snapshots and use Cloud Backup to back up files. migrate-controller also allows you to reduce the recovery time objective (RTO) of data restoration by using snapshots.

Usage notes

You can use migrate-controller to back up, restore, and migrate applications. For more information, see Back up and restore applications and Migrate applications across clusters in the same region.
