TKE Backup Center provides integrated solutions for the backup, restoration and migration of containerized applications. This document describes the use cases and the core add-on of the Backup Center.
Note：
Backup Center is in beta test. To try it out, please submit a ticket.
Use cases
Backup restoration: If the resources in a cluster or namespace are deleted by misoperation, you can quickly restore them with the backup data.
Cross-cloud migration: Application data can be migrated between public clouds or between public cloud and private cloud.
Business compliance: Backup data is fetched periodically for auditing.
Core add-ons
Add-on name
Description
tke-backup
A backup add-on deployed in your cluster. It supports scheduled backup and restoration of Kubernetes resources via CRD based on the open-source tool Velero.
Notes: 
Cross-cluster backup and recovery capability requires the component version to be 1.1.0 or higher. It is recommended that you update the version timely.
It only supports the recovery of Kubernetes resource objects currently and does not support the recovery of cloud resources such as CBS and CLB.

Resource types
TKE customized backup related CRD resources are described as follows:
Resource name
Description
Backup
It specifies the backup policy for resource objects. The backup process is launched when a backup task is created. When a backup task is deleted, the underlying data stored in the backup repository COS are not deleted accordingly.
BackupSchedule
It specifies the scheduled backup policy for resource objects. A scheduled backup task is created based on it.
Restore
It restores backup data to the target TKE cluster. The restoration process is launched when you create a restoration task. When you delete a restoration task, the log of restoration operation is removed from the list.
Directions
1. Log in to the TKE console to create a backup repository. For details, see Creating a Backup Repository.
2. Create a backup policy or scheduled backup policy for the target cluster. For details, see Backup Management.
3. Restore the specified resource objects based on the backup data. For details, see Restoration Management.
