 * **SAP HANA databases on Azure VM, SQL Server databases on Azure VM**: Requires connectivity to the Azure Backup service, Azure Storage, and Microsoft Entra ID. This can be achieved by using private endpoints or by allowing access to the required public IP addresses or FQDNs. Not allowing proper connectivity to the required Azure services may lead to failure in operations like database discovery, configuring backup, performing backups, and restoring data. For complete network guidance while using NSG tags, Azure firewall, and HTTP Proxy, refer to these [SQL](backup-sql-server-database-azure-vms.md#establish-network-connectivity) and [SAP HANA](./backup-azure-sap-hana-database.md#establish-network-connectivity) articles.
