+# Quickstart for NFS backup
+## Install NFS server
+
+### 1. Prepare Storage
+
+Create the NFS PV and SC.
+
+```
+kubectl apply -f config/samples/nfs_pv.yaml 
+```
+
+> You can specify the PVC you created by modifying the `persistentVolumeClaim.claimName` in the `config/samples/nfs_server.yaml`.
+
+### 2. Create nfs server
+
+Create ReplicationController and Service.
+
+```
+kubectl apply -f config/samples/nfs_server.yaml 
+```
+
+Get `NFSServerAddress`.
+
+```
+# example
+kubectl get svc nfs-server --template={{.spec.clusterIP}}
+10.96.253.82
+```
+
+## Create a NFS backup
+
+### 1. Configure address of NFS Server.
+
+```yaml
+# config/samples/mysql_v1alpha1_backup.yaml
+NFSServerAddress: "10.96.253.82"
+```
+
+### 2. Create a backup
+
+```shell
+kubectl apply -f config/samples/mysql_v1alpha1_backup.yaml
+```
+
+>  Notice: backup cr and mysqlcluster cr must be in the same namespace.
+### 3. Verify your backup
+
+You can find the backup folder called `<cluster name>_<timestamp>`.
+
+```
+kubectl exec -it <pod name of nfs server> -- ls /exports
+index.html  initbackup  sample_2022419101946
+```
+
+ ## Restore cluster from exist NFS backup
+
+Configure the `mysql_v1alpha1_cluster.yaml`, uncomment the `nfsServerAddress` field and fill in your own configuration.
+
+ ```yaml
+ ...
+ restoreFrom: "sample_2022419101946"
+ nfsServerAddress: 10.96.253.82
+ ```
+ 
+ > Notice: restoreFrom is the folder name of a backup. You can find it on the path mounted in NFS Server.
+
+ Create cluster from NFS server backup copy:
+
+ ```
+kubectl apply -f config/samples/mysql_v1alpha1_cluster.yaml
+ ```
+
+ ## Build your own image
+
+ ```
+ docker build -f Dockerfile.sidecar -t  acekingke/sidecar:0.1 . && docker push acekingke/sidecar:0.1
+ docker build -t acekingke/controller:0.1 . && docker push acekingke/controller:0.1
+ ```
+> You can replace acekingke/sidecar:0.1 with your own tag
+
+ ## Deploy your own manager
+```shell
+make manifests
+make install 
+make deploy  IMG=acekingke/controller:0.1 KUSTOMIZE=~/radondb-mysql-kubernetes/bin/kustomize 
+```

 if you want backup to NFS server or restore from NFS server, do it as follow:
-
-## Quickstart for  NFS backup
-
-### Create NFS server
-first create your PVC, such as "neosan1", fill it to `config/samples/nfs_rc.yaml ` 
-```yaml
-...
-    volumes:
-        - name: nfs-export-fast
-          persistentVolumeClaim:
-            claimName: neosan1
-```
- ```shell
-# create the nfs pod
-kubectl apply -f config/samples/nfs_rc.yaml 
-# create the nfs service
-kubectl apply -f config/samples/nfs_server.yaml 
- ```
-if create the nfs server successful, get the then:
-
-## config `mysql_v1alpha1_backup.yaml ` and backup
-Add field in `mysql_v1alpha1_backup.yaml ` as follow:
-```yaml
-BackupToNFS: "IP of NFS server"
-```
-use commadn as follow to backup
-```shell
-kubectl apply -f config/samples/mysql_v1alpha1_backup.yaml
-```
- 
- ## Restore cluster from exist NFS backup
- first, configure the `mysql_v1alpha1_cluster.yaml`, uncomment the `restoreFromNFS` field:
- ```yaml
- ....
- restoreFrom: "backup_202196152239"
- restoreFromNFS : 10.96.253.82
- ```
- `backup_202196152239` is the nfs server backup path, change it to yours.
- the `10.96.253.82` is the NFS server ip, change it to yours.
- use command as follow to create cluster from NFS server backup copy:
-
- ## build your own image
- such as :
- ```
- docker build -f Dockerfile.sidecar -t  acekingke/sidecar:0.1 . && docker push acekingke/sidecar:0.1
- docker build -t acekingke/controller:0.1 . && docker push acekingke/controller:0.1
- ```
- you can replace acekingke/sidecar:0.1 with your own tag

- ## deploy your own manager
-```shell
-make manifests
-make install 
-make deploy  IMG=acekingke/controller:0.1 KUSTOMIZE=~/radondb-mysql-kubernetes/bin/kustomize
