+= Configuring AWS STS Manual Mode for OADP
+
+AWS Security Token Service (STS) manual mode is the recommended way to access AWS S3 for OADP (OpenShift Application Data Protection) operations. This approach uses the OpenShift cluster's signed ServiceAccount tokens that are automatically refreshed hourly and exchanged for temporary AWS credentials via AWS IAM OpenID Connect (OIDC) Identity Provider, eliminating the need for long-term static AWS credentials.
+
+[NOTE]
+====
+This configuration requires `credentialsMode: Manual` during cluster installation and uses the Cloud Credential Operator (`ccoctl`) to set up the STS infrastructure, including ServiceAccount signing keys, S3 buckets or CloudFront distributions for OIDC configuration, and IAM roles for each component.
+====
+
+.Prerequisites
+
+* You have an OpenShift cluster installed on Amazon Web Services with STS manual mode configured.
+* You have the AWS CLI (`aws`) installed and configured.
+* You have access to the OpenShift cluster as a user with `cluster-admin` privileges.
+* You have an AWS account with appropriate permissions.
+
+.Procedure
+
+. Set up environment variables for your configuration:
++
+[source,bash]
+----
+# Get cluster information
+export API_URL=$(oc whoami --show-server)
+export CLUSTER_NAME=$(echo "$API_URL" | sed 's|https://api\.||' | sed 's|\..*||')
+export CLUSTER_BASE_DOMAIN=$(oc get dns cluster -o jsonpath='{.spec.baseDomain}')
+
+# Get AWS information
+export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
+export AWS_REGION=$(aws configure get region)
+
+# Set names for OADP resources
+export OIDC_BUCKET_NAME="${CLUSTER_NAME}-oidc"
+export VELERO_BUCKET_NAME="${CLUSTER_NAME}-velero-backups"
+export ROLE_NAME="openshift-adp-controller-manager"
+----
+
+. Create an S3 bucket for Velero backups:
++
+[source,bash]
+----
+# Create backup storage bucket
+aws s3 mb s3://${VELERO_BUCKET_NAME} --region ${AWS_REGION}
+
+# Enable versioning for backup integrity
+aws s3api put-bucket-versioning \
+    --bucket ${VELERO_BUCKET_NAME} \
+    --versioning-configuration Status=Enabled
+
+----
+
+. Get the OIDC issuer URL from your OpenShift cluster:
++
+[source,bash]
+----
+export SERVICE_ACCOUNT_ISSUER=$(oc get authentication.config.openshift.io cluster -o json | jq -r .spec.serviceAccountIssuer)
+echo "OIDC Issuer: $SERVICE_ACCOUNT_ISSUER"
+
+# Extract the issuer hostname for AWS IAM
+export OIDC_ISSUER_HOST=$(echo "$SERVICE_ACCOUNT_ISSUER" | sed 's|https://||')
+----
+
+. Create IAM OIDC Identity Provider:
++
+[source,bash]
+----
+# Get the OIDC thumbprint (this is typically the same for all OpenShift clusters)
+export OIDC_THUMBPRINT=$(echo | openssl s_client -servername ${OIDC_ISSUER_HOST} -connect ${OIDC_ISSUER_HOST}:443 2>/dev/null | openssl x509 -fingerprint -noout -sha1 | sed 's/://g' | awk -F= '{print tolower($2)}')
+
+# Create OIDC Identity Provider
+aws iam create-open-id-connect-provider \
+    --url "${SERVICE_ACCOUNT_ISSUER}" \
+    --client-id-list "openshift" "sts.amazonaws.com" \
+    --thumbprint-list "${OIDC_THUMBPRINT}"
+
+# Get the OIDC Provider ARN
+export OIDC_PROVIDER_ARN=$(aws iam list-open-id-connect-providers --query "OpenIDConnectProviderList[?ends_with(Arn, '${OIDC_ISSUER_HOST}')].Arn" --output text)
+echo "OIDC Provider ARN: $OIDC_PROVIDER_ARN"
+----
+
+. Create IAM role for OADP with trust policy:
++
+[source,bash]
+----
+# Create trust policy for the OADP role

+== Alternative: Using Cloud Storage API for Automated Bucket Management
+
+Instead of manually creating S3 buckets, you can use the OADP Cloud Storage API to automatically manage bucket creation and configuration. This approach requires OADP operator version with Cloud Storage API support.
+
+.Prerequisites for Cloud Storage API
+
+* OADP operator with Cloud Storage API functionality enabled
+* The same AWS STS configuration as above
+
+.Procedure for Cloud Storage API
+
+. Create a CloudStorage resource instead of manually creating buckets:

++
+[source,bash]
+----
+oc get cloudstorage aws-backup-storage -n openshift-adp -o yaml

+----
+
+. Wait for bucket creation and verify:
++
+[source,bash]
+----
+# Check if bucket was created in S3
+aws s3 ls s3://${VELERO_BUCKET_NAME}/
+
+# Verify bucket policies and configuration
+aws s3api get-bucket-policy --bucket ${VELERO_BUCKET_NAME}
+----
+
+. Monitor the CloudStorage controller logs:
++
+[source,bash]
+----
+# Check operator logs for CloudStorage operations
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i cloudstorage
+
+# Check for AWS-specific operations
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i aws
+----
+
+[WARNING]
+====
+CloudStorage resources are protected by a finalizer (`oadp.openshift.io/bucket-protection`) to prevent accidental deletion of buckets containing backup data. To delete a CloudStorage resource, you must first add the deletion annotation:
+
+[source,bash]
+----
+# Add deletion annotation before attempting to delete
+oc annotate cloudstorage aws-backup-storage -n openshift-adp \
+    oadp.openshift.io/cloudstorage-delete=true --overwrite
+
+# Then delete the CloudStorage resource
+oc delete cloudstorage aws-backup-storage -n openshift-adp
+----
+
+Without this annotation, the deletion will hang indefinitely as the finalizer prevents removal.
+
+Alternatively, if you want to remove the CloudStorage resource from OpenShift without deleting the S3 bucket in AWS, you can manually remove the finalizer:
+
+[source,bash]
+----
+# Remove finalizer to delete CloudStorage CR without deleting the S3 bucket
+oc patch cloudstorage aws-backup-storage -n openshift-adp --type json \
+    -p='[{"op": "remove", "path": "/metadata/finalizers"}]'
+----
+====
+
+The CloudStorage API will automatically:
+
+* Create the S3 bucket if it doesn't exist (with `creationPolicy: CreateIfNotExists`)
+* Configure appropriate bucket policies for the IAM role
+* Set up regional configuration based on the specified region
+* Handle authentication through the referenced credential secret
+* Protect bucket resources with finalizers to prevent accidental deletion
+

+====
+Ensure that the IAM role has the required permissions for both S3 bucket operations and EC2 volume snapshots for full OADP functionality.

+.Troubleshooting
+
+If you encounter authentication issues:
+
+* Verify that the IAM role has the correct trust policy for both service accounts
+* Check that the OIDC Identity Provider is correctly configured
+* Ensure the service account annotations match the IAM role ARN
+* Review the Velero logs for detailed error messages:
++
+[source,bash]
+----
+oc logs -n openshift-adp deployment/velero
+----
+
+* Check the CloudStorage controller logs for bucket management issues:
++
+[source,bash]
+----
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i cloudstorage
+----
+
+* Validate AWS STS token exchange:

+----
+# Test STS assume role from within a pod
+oc exec -n openshift-adp ${VELERO_POD} -- aws sts get-caller-identity
+----

+= Configuring OADP for ROSA with STS
+
+Red Hat OpenShift Service on AWS (ROSA) with Security Token Service (STS) provides enhanced security for OADP (OpenShift Application Data Protection) operations by using pre-configured IAM roles instead of long-term AWS credentials. ROSA STS clusters automatically provide the necessary OIDC identity provider and trust relationships, requiring only application-level configuration for OADP.
+
+[NOTE]
+====
+ROSA STS clusters are pre-configured with OIDC identity providers for authentication. This procedure creates a dedicated IAM role for OADP operations with appropriate trust relationships and permissions, following ROSA-specific naming conventions and tagging requirements.
+====
+
+.Prerequisites
+
+* You have a ROSA cluster with STS enabled.
+* You have the ROSA CLI (`rosa`) installed and configured.
+* You have the AWS CLI (`aws`) installed and configured with appropriate IAM permissions.
+* You have access to the ROSA cluster as a user with `cluster-admin` privileges.
+* You have permissions to create IAM roles and policies in your AWS account.
+
+.Procedure
+
+. Set up environment variables for your ROSA cluster:
++
+[source,bash]
+----
+# Get ROSA cluster information
+export CLUSTER_NAME=$(oc get infrastructure cluster -o jsonpath='{.status.infrastructureName}')
+export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
+export AWS_REGION=$(rosa describe cluster -c ${CLUSTER_NAME} --output json | jq -r .region.id)
+
+# Get OIDC endpoint for the cluster
+export OIDC_ENDPOINT=$(oc get authentication.config.openshift.io cluster -o jsonpath='{.spec.serviceAccountIssuer}' | sed 's|https://||')
+
+# Set role name and backup bucket
+export ROLE_NAME="${CLUSTER_NAME}-openshift-oadp-aws-cloud-credentials"
+export ROLE_ARN="arn:aws:iam::${AWS_ACCOUNT_ID}:role/${ROLE_NAME}"
+export VELERO_BUCKET_NAME="${CLUSTER_NAME}-oadp-storage"

+ROSA STS clusters automatically provide the OIDC identity provider configuration and trust relationships required for STS token exchange. The credential files use `web_identity_token_file` pointing to OpenShift service account tokens that are automatically rotated by the platform.
+====
+
+[IMPORTANT]
+====
+* **Restic is unsupported** in ROSA environments - use Kopia instead for file system backups
+* **Data Mover** is not currently supported in ROSA clusters - use native AWS S3 tools for cross-region operations
+* Ensure your ROSA cluster has appropriate AWS service quotas for EBS snapshots and S3 operations
+* Only specific storage classes are supported: `gp3-csi`, `gp2-csi`, `gp3`, `gp2`
+====
+
+.Troubleshooting
+
+If you encounter issues with OADP on ROSA STS:
+
+* Verify ROSA cluster status and OIDC configuration:
++
+[source,bash]
+----
+rosa describe cluster -c ${CLUSTER_NAME}
+rosa logs install -c ${CLUSTER_NAME} --tail 50
+----
+
+* Check IAM role configuration:
++
+[source,bash]
+----
+# Extract role name from ARN for validation
+ROLE_NAME=$(echo ${ROLE_ARN} | awk -F'/' '{print $NF}')
+
+# Check role exists and trust policy
+aws iam get-role --role-name ${ROLE_NAME}
+aws iam list-role-policies --role-name ${ROLE_NAME}
+aws iam list-attached-role-policies --role-name ${ROLE_NAME}
+----
+
+* Validate OIDC provider configuration:
++
+[source,bash]
+----
+# List OIDC providers in the account
+aws iam list-open-id-connect-providers
+
+# Get OIDC endpoint from cluster for validation
+OIDC_ENDPOINT=$(oc get authentication.config.openshift.io cluster -o json | jq -r .spec.serviceAccountIssuer)
+echo "Cluster OIDC Endpoint: $OIDC_ENDPOINT"
+
+# Validate the OIDC provider exists
+aws iam get-open-id-connect-provider --open-id-connect-provider-arn arn:aws:iam::${AWS_ACCOUNT_ID}:oidc-provider/${OIDC_ENDPOINT#https://}
+----
+
+* Review OADP operator logs for ROSA-specific issues:
++
+[source,bash]
+----
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i rosa
+oc logs -n openshift-adp deployment/velero | grep -i sts
+----
+
+* Test S3 bucket access and credentials:
++
+[source,bash]
+----
+# Test bucket access with current credentials
+aws s3 ls s3://${VELERO_BUCKET_NAME}/
+
+# Check credentials secret in OpenShift
+oc get secret cloud-credentials-aws -n openshift-adp -o jsonpath='{.data.credentials}' | base64 -d
+
+# Test STS authentication
+aws sts get-caller-identity
+----
+
+* Check ROSA-specific networking considerations:

+== Cleanup Procedures
+
+To remove OADP and associated AWS resources:
+
+. Remove OADP operator and resources:
++
+[source,bash]
+----
+# Delete DataProtectionApplication
+oc delete dpa --all -n openshift-adp
+
+# Delete CloudStorage resources if used
+oc delete cloudstorage --all -n openshift-adp
+
+# Delete OADP namespace
+oc delete namespace openshift-adp
+
+# Remove OADP operator subscription
+oc delete subscription oadp-operator -n openshift-operators 2>/dev/null || true
+
+# Remove operator CSV
+oc delete csv $(oc get csv -n openshift-operators | grep oadp | awk '{print $1}') -n openshift-operators 2>/dev/null || true
+----
+
+. Clean up AWS resources:
++
+[source,bash]
+----
+# Delete S3 bucket contents and bucket
+aws s3 rm s3://${VELERO_BUCKET_NAME} --recursive 2>/dev/null || true
+aws s3 rb s3://${VELERO_BUCKET_NAME} 2>/dev/null || echo "Bucket ${VELERO_BUCKET_NAME} not found or already deleted"
+
+# Remove IAM role policy
+aws iam delete-role-policy \
+    --role-name ${ROLE_NAME} \
+    --policy-name openshift-oadp-aws-cloud-credentials 2>/dev/null || echo "Policy not found"
+
+# Delete IAM role
+aws iam delete-role --role-name ${ROLE_NAME} 2>/dev/null || echo "Role ${ROLE_NAME} not found"
+
+# Clean up temporary files
+rm -f trust-policy.json oadp-policy.json
+rm -rf ${SCRATCH}
+
+echo "OADP cleanup completed"
+----
+
+[IMPORTANT]
+====
+* Verify all backups are no longer needed before deleting the S3 bucket
+* The IAM role and OIDC provider are cluster-specific and should only be deleted if the cluster is being decommissioned
+* Consider backing up any important data before running cleanup procedures

+= Configuring Microsoft Entra Workload ID for OADP
+
+Microsoft Entra Workload ID is the recommended way to access Azure Storage for OADP (OpenShift Application Data Protection) operations. This approach uses the OpenShift cluster's signed Kubernetes ServiceAccount tokens, which are automatically rotated hourly and exchanged for Azure AD access tokens, eliminating the need for long-term client secrets.
+
+[NOTE]
+====
+This configuration requires `credentialsMode: Manual` during cluster installation and uses the Cloud Credential Operator (`ccoctl`) to set up the workload identity infrastructure, including OIDC issuer configuration and User-Assigned Managed Identities.
+====
+
+.Prerequisites
+
+* You have an OpenShift cluster installed on Microsoft Azure with Microsoft Entra Workload ID configured.
+* You have the Azure CLI (`az`) installed and configured.
+* You have access to the OpenShift cluster as a user with `cluster-admin` privileges.
+* You have an Azure subscription with appropriate permissions.
+
+[NOTE]
+====
+If your OpenShift cluster was not originally installed with Microsoft Entra Workload ID, you can enable short-term credentials after installation. This post-installation configuration is supported specifically for Azure clusters.
+====
+
+[id="post-install-enable-workload-id_{context}"]
+== Enabling Microsoft Entra Workload ID After Installation
+
+If your cluster was installed with long-term credentials, you can switch to Microsoft Entra Workload ID authentication after installation. This is only supported on Azure.
+
+.Prerequisites for post-installation configuration
+
+* An existing OpenShift cluster on Azure using long-term credentials
+* Cluster administrator access
+* Azure CLI with appropriate permissions
+
+.Procedure to enable Microsoft Entra Workload ID post-installation
+
+. Update the cluster authentication configuration to enable token authentication:
++
+[source,bash]
+----
+# Enable short-term credential support
+oc patch authentication.config.openshift.io cluster \
+    --type='merge' \
+    --patch='{"spec":{"type":"IntegratedOAuth","oauthMetadata":{"name":"oauth-openshift"}}}'
+
+# Verify the service account issuer is configured
+oc get authentication.config.openshift.io cluster -o jsonpath='{.spec.serviceAccountIssuer}'
+----
+
+. Follow the standard Microsoft Entra Workload ID configuration procedure below to complete the setup.
+
+[IMPORTANT]
+====
+After enabling Microsoft Entra Workload ID on an existing cluster, you must update all cluster components that use cloud credentials, including OADP, to use the new authentication method.
+====
+
+.Procedure
+
+. Set up environment variables for your configuration:
++
+[source,bash]
+----
+# Get cluster information
+export API_URL=$(oc whoami --show-server)
+export CLUSTER_NAME=$(echo "$API_URL" | sed 's|https://api\.||' | sed 's|\..*||')
+export CLUSTER_RESOURCE_GROUP="${CLUSTER_NAME}-rg"
+
+# Get Azure information
+export AZURE_SUBSCRIPTION_ID=$(az account show --query id -o tsv)
+export AZURE_TENANT_ID=$(az account show --query tenantId -o tsv)
+
+# Set names for resources
+export IDENTITY_NAME="velero"
+export APP_NAME="velero-${CLUSTER_NAME}"
+export STORAGE_ACCOUNT_NAME=$(echo "velero${CLUSTER_NAME}" | tr -d '-' | tr '[:upper:]' '[:lower:]' | cut -c1-24)
+export CONTAINER_NAME="velero"
+----
+
+. Create an Azure Managed Identity for OADP:
++
+[source,bash]
+----
+# Create managed identity
+az identity create \
+    --subscription "$AZURE_SUBSCRIPTION_ID" \
+    --resource-group "$CLUSTER_RESOURCE_GROUP" \
+    --name "$IDENTITY_NAME"
+
+# Get identity details
+export IDENTITY_CLIENT_ID=$(az identity show -g "$CLUSTER_RESOURCE_GROUP" -n "$IDENTITY_NAME" --query clientId -o tsv)
+export IDENTITY_PRINCIPAL_ID=$(az identity show -g "$CLUSTER_RESOURCE_GROUP" -n "$IDENTITY_NAME" --query principalId -o tsv)
+----
+
+. Grant the required Azure roles to the managed identity:
++
+[source,bash]
+----
+# Get subscription ID for role assignments
+export SUBSCRIPTION_ID=$(az account show --query id -o tsv)
+
+# Required roles for OADP operations
+REQUIRED_ROLES=(
+    "Contributor"
+    "Storage Blob Data Contributor" 
+    "Disk Snapshot Contributor"
+)
+
+for role in "${REQUIRED_ROLES[@]}"; do
+    echo "Assigning role: $role"
+    az role assignment create \
+        --assignee "$IDENTITY_PRINCIPAL_ID" \
+        --role "$role" \
+        --scope "/subscriptions/$SUBSCRIPTION_ID"
+done
+----
+
+. Create an Azure Storage Account and container:
++
+[source,bash]
+----
+# Create storage account
+az storage account create \
+    --name "$STORAGE_ACCOUNT_NAME" \
+    --resource-group "$CLUSTER_RESOURCE_GROUP" \
+    --location "$(az group show -n $CLUSTER_RESOURCE_GROUP --query location -o tsv)" \
+    --sku Standard_LRS \
+    --kind StorageV2
+
+# Create container for backups
+az storage container create \
+    --name "$CONTAINER_NAME" \
+    --account-name "$STORAGE_ACCOUNT_NAME" \
+    --auth-mode login
+----
+
+. Get the OIDC issuer URL from your OpenShift cluster:
++
+[source,bash]
+----
+export SERVICE_ACCOUNT_ISSUER=$(oc get authentication.config.openshift.io cluster -o json | jq -r .spec.serviceAccountIssuer)
+echo "OIDC Issuer: $SERVICE_ACCOUNT_ISSUER"
+----
+
+. Configure Microsoft Entra Workload ID Federation:
++
+[source,bash]
+----
+# Create federated identity credential for Velero service account
+az identity federated-credential create \
+    --name "velero-federated-credential" \
+    --identity-name "$IDENTITY_NAME" \
+    --resource-group "$CLUSTER_RESOURCE_GROUP" \
+    --issuer "$SERVICE_ACCOUNT_ISSUER" \
+    --subject "system:serviceaccount:openshift-adp:velero"
+
+# Create federated identity credential for OADP controller manager
+az identity federated-credential create \
+    --name "oadp-controller-federated-credential" \
+    --identity-name "$IDENTITY_NAME" \
+    --resource-group "$CLUSTER_RESOURCE_GROUP" \
+    --issuer "$SERVICE_ACCOUNT_ISSUER" \
+    --subject "system:serviceaccount:openshift-adp:openshift-adp-controller-manager"
+----
+
+. Create the OADP namespace if it doesn't exist:
++
+[source,bash]
+----
+oc create namespace openshift-adp
+----
+
+. Annotate the service accounts to use Microsoft Entra Workload ID:
++
+[source,bash]
+----
+oc annotate serviceaccount velero -n openshift-adp \
+    azure.workload.identity/client-id="$IDENTITY_CLIENT_ID" --overwrite
+
+oc annotate serviceaccount openshift-adp-controller-manager -n openshift-adp \
+    azure.workload.identity/client-id="$IDENTITY_CLIENT_ID" --overwrite
+----
+
+[id="oadp-azure-cloud-storage-api_{context}"]
+== Alternative: Using Cloud Storage API for Automated Container Management
+
+Instead of manually creating storage containers, you can use the OADP Cloud Storage API to automatically manage container creation and configuration. This approach requires OADP operator version with Cloud Storage API support.
+
+.Prerequisites for Cloud Storage API
+
+* OADP operator with Cloud Storage API functionality enabled
+* The same Microsoft Entra Workload ID configuration as above
+
+.Procedure for Cloud Storage API
+
+. Create a CloudStorage resource instead of manually creating containers:
++
+[source,yaml]
+----
+cat <<EOF | oc apply -f -
+apiVersion: oadp.openshift.io/v1alpha1
+kind: CloudStorage
+metadata:
+  name: azure-backup-storage
+  namespace: openshift-adp

+  provider: azure
+  creationSecret:
+    name: cloud-credentials-azure
+    key: azurekey  # Required key name for Azure provider
+  config:
+    storageAccount: ${STORAGE_ACCOUNT_NAME}
+  creationPolicy: CreateIfNotExists
+EOF
+----
+
+. Create the DataProtectionApplication with Cloud Storage API reference:
++
+[source,yaml]
+----
+cat <<EOF | oc apply -f -
+apiVersion: oadp.openshift.io/v1alpha1
+kind: DataProtectionApplication
+metadata:
+  name: dpa-azure-workload-id-cloudstorage

+        - azure
+        - openshift
+        - csi
+  backupLocations:
+    - name: default
+      bucket:
+        # Reference the CloudStorage resource instead of direct container
+        cloudStorageRef:

+          resourceGroup: ${CLUSTER_RESOURCE_GROUP}
+          subscriptionId: ${AZURE_SUBSCRIPTION_ID}
+EOF
+----
+
+. Verify the CloudStorage resource status:
++
+[source,bash]
+----
+oc get cloudstorage azure-backup-storage -n openshift-adp -o yaml

++
+[source,bash]
+----
+# Check if container was created in Azure Storage
+az storage container list --account-name ${STORAGE_ACCOUNT_NAME} --auth-mode login --query "[].name" -o tsv
+
+# Verify container access
+az storage container show --name ${CONTAINER_NAME} --account-name ${STORAGE_ACCOUNT_NAME} --auth-mode login
+----
+
+. Monitor the CloudStorage controller logs:
++
+[source,bash]
+----
+# Check operator logs for CloudStorage operations
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i cloudstorage
+
+# Check for Azure-specific operations
+oc logs -n openshift-adp deployment/oadp-operator-controller-manager | grep -i azure
+----
+
+[WARNING]
+====
+CloudStorage resources are protected by a finalizer (`oadp.openshift.io/bucket-protection`) to prevent accidental deletion of containers containing backup data. To delete a CloudStorage resource, you must first add the deletion annotation:
+
+[source,bash]
+----
+# Add deletion annotation before attempting to delete
+oc annotate cloudstorage azure-backup-storage -n openshift-adp \
+    oadp.openshift.io/cloudstorage-delete=true --overwrite
+
+# Then delete the CloudStorage resource
+oc delete cloudstorage azure-backup-storage -n openshift-adp
+----
+
+Without this annotation, the deletion will hang indefinitely as the finalizer prevents removal.
+
+Alternatively, if you want to remove the CloudStorage resource from OpenShift without deleting the Azure storage container, you can manually remove the finalizer:
+
+[source,bash]
+----
+# Remove finalizer to delete CloudStorage CR without deleting the Azure container
+oc patch cloudstorage azure-backup-storage -n openshift-adp --type json \
+    -p='[{"op": "remove", "path": "/metadata/finalizers"}]'
+----
+====
+
+The CloudStorage API will automatically:
+
+* Create the storage container if it doesn't exist (with `creationPolicy: CreateIfNotExists`)
+* Configure appropriate access permissions for the managed identity
+* Handle authentication through the referenced credential secret
+* Manage container lifecycle and cleanup operations
+* Protect container resources with finalizers to prevent accidental deletion
+
+== Standard Configuration (Manual Container Creation)
+
+. Create the DataProtectionApplication configuration for manual container setup:

+= Configuring Google Workload Identity Federation for OADP
+
+Google Workload Identity Federation is the recommended way to access Google Cloud Storage for OADP (OpenShift Application Data Protection) operations. This approach uses the OpenShift cluster's OIDC identity provider to generate short-lived `external_account` credentials that are automatically rotated hourly, eliminating the need for long-term service account keys.
+
+[NOTE]
+====
+This configuration requires `credentialsMode: Manual` during cluster installation and uses the Cloud Credential Operator (`ccoctl`) to set up the workload identity infrastructure, including signing keys, workload identity pools, and Google Cloud Storage buckets for OIDC configuration.

+
+.Prerequisites
+
+* You have an OpenShift cluster installed on Google Cloud Platform with Workload Identity configured.
+* You have the Google Cloud CLI (`gcloud`) installed and configured.
+* You have access to the OpenShift cluster as a user with `cluster-admin` privileges.
+* You have a Google Cloud Project with appropriate permissions.

+----
+
+[WARNING]
+====
+CloudStorage resources are protected by a finalizer (`oadp.openshift.io/bucket-protection`) to prevent accidental deletion of buckets containing backup data. To delete a CloudStorage resource, you must first add the deletion annotation:
+
+[source,bash]
+----
+# Add deletion annotation before attempting to delete
+oc annotate cloudstorage gcp-backup-storage -n openshift-adp \
+    oadp.openshift.io/cloudstorage-delete=true --overwrite
+
+# Then delete the CloudStorage resource
+oc delete cloudstorage gcp-backup-storage -n openshift-adp
+----
+
+Without this annotation, the deletion will hang indefinitely as the finalizer prevents removal.
+
+Alternatively, if you want to remove the CloudStorage resource from OpenShift without deleting the GCS bucket in Google Cloud, you can manually remove the finalizer:
+
+[source,bash]
+----
+# Remove finalizer to delete CloudStorage CR without deleting the GCS bucket
+oc patch cloudstorage gcp-backup-storage -n openshift-adp --type json \
+    -p='[{"op": "remove", "path": "/metadata/finalizers"}]'
+----
+====
+
+The CloudStorage API will automatically:
+
+* Create the bucket if it doesn't exist (with `creationPolicy: CreateIfNotExists`)
+* Configure appropriate IAM permissions for the service account
+* Set up regional configuration based on the specified region
+* Handle authentication through the referenced credential secret
+* Protect bucket resources with finalizers to prevent accidental deletion
+
+== Standard Configuration (Manual Bucket Creation)
+
+. Create the DataProtectionApplication configuration for manual bucket setup:

+[source,yaml]

+
+. Verify that the OADP operator pods are running:
++

+----
+
+[NOTE]
+====
+With Workload Identity Federation configured, OpenShift components use short-lived `external_account` credentials instead of long-lived `service_account` credentials. The credential secrets are automatically populated with temporary tokens that are rotated hourly using the OIDC identity provider and Google Security Token Service (STS).
+====
+
+[IMPORTANT]
+====
+Volume Snapshot Location (VSL) backups may finish with a `PartiallyFailed` phase when using WIF. This is a known limitation. CSI snapshots work correctly with this configuration.
+====
+
+.Troubleshooting
+
+If you encounter authentication issues:
+
+* Verify that the service account annotation is correct
+* Check that the IAM binding includes the correct principal format
+* Ensure the Google Cloud service account has the required permissions
+* Review the Velero logs for detailed error messages:

+//
+// This approach is designed to be compatible with Velero's Azure credential handling
+// without requiring upstream changes to Velero. Velero expects Azure credentials as:
+// https://github.com/vmware-tanzu/velero/blob/main/pkg/util/azure/credential.go
+// - Environment variables (for Workload Identity)
+// - Direct secret values (for storage keys and service principals)
+//
+// By handling credentials directly in our Azure implementation, we maintain compatibility
+// with Velero's expectations while avoiding the complexity of temporary credential files.
+// The Azure SDK supports creating credentials programmatically from values, making the
+// file-based approach unnecessary.
+//

+// 1. Storage Account Key - uses NewSharedKeyCredential
