+# Backup and Restore
+
+>MKE 4 backup is enabled by default.
+
+MKE 4 supports backup and restore of cluster data through the use of the
+[Velero](https://velero.io/) addon.
+
+## Configuration
+
+The `backup` section of the MKE4 configuration file renders as follows:
+
+```yaml
+backup:
+  enabled: true
+  storage_provider:
+    type: InCluster
+    in_cluster_options:
+      exposed: true
+      distributed: false
+```
+By default, MKE 4 supports backups that use the in-cluster storage
+provider, as indicated in the ``type`` option setting of ``InCluster``. MKE 4
+in-cluster backups are implemented using the [MinIO
+addon](https://microk8s.io/docs/addon-minio).
+
+The `exposed` option setting of ``true`` indicates that the MinIO service is
+exposed through NodePort, which Velero requires to function correctly. Core
+backup functionality should work, however, even if
+the service is not exposed.
+
+The `distributed` option configures MinIO storage to run in distributed mode.
+
+Refer to the following table for detail on all of the conifguration file
+``backup`` fields:
+
+| Field                                                      | Description                                                                          | Valid values        |  Default  |

+| storage_provider.external_options.region                   | Region in which the bucket exists.                                                   | ""                  |     ""    |

+## Create backups and restores
+
+For information on how to create backups and run restores for both storage
+provider types, refer to:
+
+- In-cluster storage provider: [in_cluster.md](./in_cluster.md)
+- External storage provider: [external.md](./external.md)
+
+## Existing Limitations
+
+- Scheduled backups, an MKE 3 feature that is planned for integration to MKE 4, have not yet been implemented.
+
+- Backups must currently be restored in the same cluster in which
+the backup was taken, and thus restoring a backup to a
+new set of nodes is not yet supported for the in-cluster storage provider.

 # Backup and Restore Using External Storage Providers
 
-It is possible to configure MKE to store backups and restores externally, for example in object storage provided by a public cloud provider. Currently only AWS S3 is supported as an external backup store.
+You can configure MKE 4 to store backups and restores externally, for example
+in object storage provided by a public cloud provider.
+
+>AWS S3 is currently the only supported external backup store
+>that MKE 4 supports.
 
 ## Configuration
 
-Prior to modifying the MKE configuration file, create an IAM credentials file. This file should look like below
-```
-[386383511305_docker-testing]
-aws_access_key_id=key
-aws_secret_access_key=secret
-aws_session_token=token
-```
+1. Copy the credentials information from the AWS console to create an IAM
+credentials file.
 
-This can be easily copied from AWS console below:
+   ![img.png](img.png)
 
-![img.png](img.png)
+2. Edit the `storage_provider` section of the mke configuration file to point
+to the IAM credentials file, including the profile name.
 
-Once the Credentials file is created, update the `storage_provider` section of the mke config file to point to the created creds file including the profile name. Additionally, you need to create an S3 bucket and point the configuration to the correct bucket and region. 
+3. Create an S3 bucket and configure the IAM configuration file to point to the
+   bucket and region.

-  storage_provider:
-    type: External
-    external_options:
-      provider: aws
-      bucket: bucket_name
-      region: us-west-2
-      credentials_file_path: "/path/to/iamcredentials"
-      credentials_file_profile: "386383511305_docker-testing"

+         credentials_file_profile: "386383511305_docker-testing"
+   ```
 
-Once AWS backup storage has been configured and the mke config file applied, check that the `BackupStorageLocation` CR exists and is ready. This may take a few minutes after `mkectl apply` is run.
