+
+toc::[]
+
+In hosted clusters on bare-metal or {aws-first} platforms, you can automate some backup and restore steps by using the {oadp-first} Operator.
+
+The process involves the following steps:
+
+. Configuring {oadp-short}
+. Defining a Data Protection Application (DPA)
+. Backing up the data plane workload
+. Backing up the control plane workload
+. Restoring a hosted cluster by using {oadp-short}
+
+[id="hcp-auto-dr-prereqs_{context}"]
+== Prerequisites
+
+You must meet the following prerequisites on the management cluster:
+
+* You xref:../../backup_and_restore/application_backup_and_restore/installing/oadp-installing-operator.adoc#oadp-installing-operator[installed the {oadp-short} Operator].
+* You created a storage class.
+* You have access to the cluster with `cluster-admin` privileges.
+* You have access to the {oadp-short} subscription through a catalog source.
+* You have access to a cloud storage provider that is compatible with {oadp-short}, such as S3, {azure-full}, {gcp-full}, or MinIO.
+* In a disconnected environment, you have access to a self-hosted storage provider that is compatible with {oadp-short}, for example link:https://docs.redhat.com/en/documentation/red_hat_openshift_data_foundation/[{odf-full}] or link:https://min.io/[MinIO].
+* Your {hcp} pods are up and running.

+= Backing up the control plane workload
+
+You can back up the control plane workload by creating the `Backup` custom resource (CR).
+
+To monitor and observe the backup process, see "Observing the backup and restore process".
+
+.Procedure
+
+. Create a YAML file that defines the `Backup` CR:
++
+.Example `backup-control-plane.yaml` file

+----
+====
+<1> Replace `backup_resource_name` with a name for your `Backup` resource.
+<2> Selects specific namespaces to back up objects from them. You must include your hosted cluster namespace and the hosted control plane namespace.
+<3> Replace `<hosted_cluster_namespace>` with the name of the hosted cluster namespace, for example, `clusters`.
+<4> Replace `<hosted_control_plane_namespace>` with the name of the hosted control plane namespace, for example, `clusters-hosted`.
+<5> You must create the `infraenv` resource in a separate namespace. Do not delete the `infraenv` resource during the backup process.
+<6> Enables the CSI volume snapshots and uploads the control plane workload automatically to the cloud storage.
+<7> Sets the `fs-backup` backing up method for persistent volumes (PVs) as default. This setting is useful when you use a combination of Container Storage Interface (CSI) volume snapshots and the `fs-backup` method.
++
+[NOTE]
+====
+If you want to use CSI volume snapshots, you must add the `backup.velero.io/backup-volumes-excludes=<pv_name>` annotation to your PVs.
+====
+
+. Apply the `Backup` CR by running the following command:
++
+[source,terminal]
+----
+$ oc apply -f backup-control-plane.yaml
+----
+
+.Verification
+
+* Verify that the value of the `status.phase` is `Completed` by running the following command:
++
+[source,terminal]
+----
+$ oc get backups.velero.io <backup_resource_name> -n openshift-adp \
+  -o jsonpath='{.status.phase}'
+----
+
+.Next steps
+
+* Restore the hosted cluster by using {oadp-short}.

+= Automating the backup and restore process by using a DPA
+
+You can automate parts of the backup and restore process by using a Data Protection Application (DPA). When you use a DPA, the steps to pause and restart the reconciliation of resources are automated. The DPA defines information including backup locations and Velero pod configurations.
+
+You can create a DPA by defining a `DataProtectionApplication` object.
+
+.Procedure
+
+* If you use a bare-metal platform, you can create a DPA by completing the following steps:

+. Create a manifest file similar to the following example:
