TKE Backup Center provides integrated solutions for the backup, restoration and migration of applications. This document describes how to restore resources from the target cluster where the backup task has been created.
Note:
Only backup and restoration in a cluster are supported. Cross-cluster migration is not available currently.
Prerequisite
Create a backup task in the target cluster.
Directions
Creating a restoration task
1. Log in to the TKE console and select Backup Center > Restoration Management in the left sidebar.
2. Click Create restoration task on the page that appears.
3. Enter restoration information.
Field description:
Task name: Enter the restoration task name that meets the requirements prompted.
Backup repository: Select a backup repository you created.
Select backup: Select a backup task to restore.
Restore namespace: Select namespaces from which you want to restore resources.
All namespaces: Restore resources in all namespaces found in the backup.
Specific namespace: Restore resources in the specific namespace that is selected in the backup task.
Conflict treatment:
Do not override (recommended): The backup resource with the same name in the namespace of the target cluster will not be overridden.
Update: The backup resource with the same name in the namespace of the target cluster will be overridden.
4. Click OK.
Note:
The success of the restoration tasks cannot be guaranteed.
Deleting the backup task only removes the operation log of restoration from the restoration list.
