 SAP HANA databases are mission critical workloads that require a low recovery point objective (RPO) and a fast recovery time objective (RTO). You can now [back up SAP HANA databases running on Azure VMs](https://docs.microsoft.com/azure/backup/tutorial-backup-sap-hana-db) using [Azure Backup](https://docs.microsoft.com/azure/backup/backup-overview).
