Backing up on-premises ONTAP data to Azure Blob storage

Contributors netapp-tonacki Download PDF of this page

Complete a few steps to get started backing up data from your on-premises ONTAP systems to Azure Blob storage.

TIP

In most cases you’ll use Cloud Manager for all backup and restore operations. However, starting with ONTAP 9.9.1 you can initiate volume backup operations of your on-premises ONTAP clusters using ONTAP System Manager. See how to use System Manager to back up your volumes to the cloud using Cloud Backup.

A Beta feature released in January 2021 allows you to run compliance scans on the backed up volumes from your on-premises systems. Typically, compliance scans are free up to 1 TB of data, and then a cost for the service is applied for data over 1 TB. When combining Backup and Data Sense for your on-premises volumes, the cost for scans on those on-prem volumes is free. Learn more about how Cloud Data Sense can get your business applications and cloud environments privacy ready.

Quick start

Get started quickly by following these steps, or scroll down to the remaining sections for full details.

Number 1 Verify support for your configuration

  • You have discovered the on-premises cluster and added it to a working environment in Cloud Manager. See Discovering ONTAP clusters for details.

    • The cluster is running ONTAP 9.7P5 or later.

    • The cluster has a SnapMirror license — it is included as part of the Premium Bundle or Data Protection Bundle.

  • The cluster must have the required network connections to Blob storage and to the Connector.

  • The Connector must have the required network connections to Blob storage and to the cluster, and the required permissions.

  • You have a valid Azure subscription for the object storage space where your backups will be located.

Number 2 Enable Cloud Backup on the system

Select the working environment and click Enable next to the Backup & Compliance service in the right-panel, and then follow the setup wizard.

Number 3 Select the cloud provider and enter the provider details

Select Microsoft Azure as your provider and then enter the provider details. You’ll need to select the Azure Subscription and the region where you want to create the backups. You can also choose your own customer-managed key for data encryption instead of using the default Microsoft-managed encryption key.

Number 6 Select the volumes that you want to back up

Identify which volumes you want to back up from the cluster.

Number 7 Activate Compliance scans on the backed up volumes (optional)

Choose whether you want to have Cloud Data Sense scan the volumes that are backed up in the cloud.

Number 8 Restore your data, as needed

Choose to restore an entire backup to a new volume, or to restore individual files from the backup to an existing volume. You can restore data to a Cloud Volumes ONTAP system in Azure, or to an on-premises ONTAP system.

Requirements

Read the following requirements to make sure you have a supported configuration before you start backing up on-premises volumes to Azure Blob storage.

The following image shows each component and the connections that you need to prepare between them:

Note that when the Cloud Restore instance is deployed in the cloud, it is located in the same subnet as the Connector.

Preparing your ONTAP clusters

You need to discover your on-premises ONTAP clusters in Cloud Manager before you can start backing up volume data.

ONTAP requirements
  • ONTAP 9.7P5 and later.

  • A SnapMirror license (included as part of the Premium Bundle or Data Protection Bundle).

    Note: The "Hybrid Cloud Bundle" is not required when using the Cloud Backup service.

  • Time and time zone are set correctly.

Cluster networking requirements
  • The ONTAP cluster initiates an HTTPS connection over port 443 from the intercluster LIF to Azure Blob storage for backup and restore operations.

    ONTAP reads and writes data to and from object storage. The object storage never initiates, it just responds.

  • ONTAP requires an inbound connection from the Connector to the cluster management LIF. The Connector can reside in an Azure VNet.

  • An intercluster LIF is required on each ONTAP node that hosts the volumes you want to back up. The LIF must be associated with the IPspace that ONTAP should use to connect to object storage. Learn more about IPspaces.

    When you set up Cloud Backup, you are prompted for the IPspace to use. You should choose the IPspace that each LIF is associated with. That might be the "Default" IPspace or a custom IPspace that you created.

  • The nodes' and intercluster LIFs are able to access the internet.

  • DNS servers have been configured for the storage VM where the volumes are located. See how to configure DNS services for the SVM.

  • Note that if you use are using a different IPspace than the Default, then you might need to create a static route to get access to the object storage.

  • Update firewall rules, if necessary, to allow Cloud Backup service connections from ONTAP to object storage through port 443 and name resolution traffic from the storage VM to the DNS server over port 53 (TCP/UDP).

Creating or switching Connectors

A Connector is required to back up data to the cloud, and the Connector must be in an Azure VNet when backing up data to Azure Blob storage. You can’t use a Connector that’s deployed on-premises. You’ll either need to create a new Connector or make sure that the currently selected Connector resides in the correct provider.

Preparing networking for the Connector

Ensure that the Connector has the required networking connections.

Steps
  1. Ensure that the network where the Connector is installed enables the following connections:

    • An outbound internet connection to the Cloud Backup service over port 443 (HTTPS)

    • An HTTPS connection over port 443 to your Blob object storage

    • An HTTPS connection over port 443 to your ONTAP clusters

  2. Enable a VNet Private Endpoint to Azure storage. This is needed if you have an ExpressRoute or VPN connection from your ONTAP cluster to the VNet and you want communication between the Connector and Blob storage to stay in your virtual private network.

Supported regions

You can create backups from on-premises systems to Azure Blob in all regions where Cloud Volumes ONTAP is supported. You specify the region where the backups will be stored when you set up the service.

License requirements

Before your 30-day free trial of the Cloud Backup service expires, you need to subscribe to a pay-as-you-go (PAYGO) Cloud Manager Marketplace offering from Azure, or purchase and activate a Cloud Backup BYOL license from NetApp. These licenses are for the account and can be used across multiple systems.

  • For Cloud Backup PAYGO licensing, you’ll need a subscription to the Azure Cloud Manager Marketplace offering to continue using Cloud Backup. Billing for Cloud Backup is done through this subscription.

  • For Cloud Backup BYOL licensing, you don’t need a subscription. You need the serial number from NetApp that enables you to use the service for the duration and capacity of the license. Learn how to manage your BYOL licenses.

You need to have an Azure subscription for the object storage space where your backups will be located.

A SnapMirror license is required on the cluster. Note that the "Hybrid Cloud Bundle" is not required when using Cloud Backup.

Preparing Azure Blob storage for backups

  1. If your virtual or physical network uses a proxy server for internet access, ensure that the Cloud Restore virtual machine has outbound internet access to contact the following endpoints.

    Endpoints Purpose

    http://olcentgbl.trafficmanager.net
    https://olcentgbl.trafficmanager.net

    Provides CentOS packages for the Cloud Restore virtual machine.

    http://cloudmanagerinfraprod.azurecr.io
    https://cloudmanagerinfraprod.azurecr.io

    Cloud Restore virtual machine image repository.

  2. You use choose your own custom-managed keys for data encryption in the activation wizard instead of using the default Microsoft-managed encryption keys. In this case you will need to have the Azure Subscription, Key Vault name, and the Key. See how to use your own keys.

  3. If you want to have a more secure connection over the public internet from your on-prem data center to the VNet, there is an option to configure an Azure Private Endpoint in the activation wizard. In this case you will need to know the VNet and Subnet for this connection. See details about using a Private Endpoint.

Enabling Cloud Backup

Enable Cloud Backup at any time directly from the on-premises working environment.

Steps
  1. From the Canvas, select the working environment and click Enable next to the Backup & Compliance service in the right-panel.

  4. Click Next after you’ve entered the provider details.

  5. Enter the networking details and click Next.

    1. The IPspace in the ONTAP cluster where the volumes you want to back up reside. The intercluster LIFs for this IPspace must have outbound internet access.

    2. Optionally, choose whether you will configure an Azure Private Endpoint. See details about using a Private Endpoint.

  7. Select the volumes that you want to back up.

    • To back up all volumes, check the box in the title row (button backup all volumes).

    • To back up individual volumes, check the box for each volume (button backup 1 volume).

      A screenshot of selecting the volumes that will be backed up.

  8. Click Activate Backup and Cloud Backup starts taking the initial backups of your volumes.

    You are prompted whether you want to run compliance scans on the backed up volumes. Cloud Data Sense scans are free when you run them on the backed up volumes (except for the cost of the deployed Cloud Data Sense instance).

    A screenshot of the page where you can choose to activate Cloud Data Sense on your backed up volumes.

  9. Click Go to Compliance to activate compliance scans on the volumes. (If you choose Close and not to scan these backed up volumes, you can always enable this functionality later from Cloud Data Sense.)

    • If an instance of Cloud Data Sense is already deployed in your environment, you are directed to the Configuration page to select the volumes you want to scan in each on-premises working environment that has backups. See how to choose the volumes.

      After you have deployed Compliance you can choose the volumes you want to scan as described above.

Result

Cloud Backup backs up your volumes from the on-premises ONTAP system, and optionally, Cloud Data Sense runs compliance scans on the backed up volumes.

You can also view the results of the compliance scans and review other features of Cloud Data Sense that can help you understand data context and identify sensitive data in your organization.

Note The scan results are not available immediately because Cloud Backup has to finish creating the backups before Cloud Data Sense can start compliance scans.
