Restore data from backup set

KubeBlocks supports restoring clusters from backups with the following instructions.

1. View backups.

   kubectl get backups

2. Restore clusters from a specific backup.

   You can set the connectionPassword.annotations of the restored cluster as that of the original cluster. The password of the original cluster can be accessed by viewing the annotation of dataprotection.kubeblocks.io/connection-password in the backup YAML file.

   kubectl apply -f - <<-'EOF'
   apiVersion: apps.kubeblocks.io/v1alpha1
   kind: Cluster
   metadata:
     name: myrestore
     namespace: default
     annotations:
       kubeblocks.io/restore-from-backup: '{"mysql":{"name":"mybackup","namespace":"default","connectionPassword": "Bw1cR15mzfldc9hzGuK4m1BZQOzha6aBb1i9nlvoBdoE9to4"}}'
   spec:
     clusterDefinitionRef: apecloud-mysql
     clusterVersionRef: ac-mysql-8.0.30
     terminationPolicy: WipeOut
     componentSpecs:
       - name: mysql
         componentDefRef: mysql
         replicas: 1
         volumeClaimTemplates:
           - name: data
             spec:
               accessModes:
                 - ReadWriteOnce
               resources:
                 requests:
                   storage: 20Gi
   EOF

3. Connect to the restored cluster for verification.

   Once the cluster status is Running, connect to the cluster for verification.
