Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Backup architecture -
✑ The backup process begins by creating a Recovery services vault in Azure. This vault will be used to store the backups and recovery points created over time.
✑ The Azure VM running SAP HANA server is registered with the vault, and the databases to be backed-up are discovered. To enable the Azure Backup service to discover databases, a preregistration script must be run on the HANA server as a root user.
✑ This script creates AZUREWLBACKUPHANAUSER DB user and a corresponding key with the same name in hdbuserstore. Refer to the setting up permissions section to understand more about what the script does.
✑ Azure Backup Service now installs the Azure Backup Plugin for HANA on the registered SAP HANA server.
✑ The AZUREWLBACKUPHANAUSER DB user created by the preregistration script is used by the Azure Backup Plugin for HANA to perform all backup and restore operations. If you attempt to configure backup for SAP HANA DBs without running this script, you might receive the following error:
UserErrorHanaScriptNotRun.
✑ To configure backup on the databases that are discovered, choose the required backup policy and enable backups.
✑ Once the backup is configured, Azure Backup service sets up the Backint parameters at the DATABASE level on the protected SAP HANA server.
✑ The Azure Backup Plugin for HANA maintains all the backup schedules and policy details. It triggers the scheduled backups and communicates with the HANA
Backup Engine through the Backint APIs.
✑ The HANA Backup Engine returns a Backint stream with the data to be backed up.
✑ All the scheduled backups and on-demand backups (triggered from the Azure portal) that are either full or differential are initiated by the Azure Backup Plugin for HANA. However, log backups are managed and triggered by HANA Backup Engineitself.

SAP HANA on Azure (Large Instances) offers two backup and restore options: Do it yourself (DIY). After you make sure that there's enough disk space, perform full database and log backups by using one of the following disk backup methods. You can back up either directly to volumes attached to the HANA Large Instance units or to NFS shares that are set up in an Azure virtual machine (VM). In the latter case, customers set up a Linux VM in Azure, attach Azure Storage to the VM, and share the storage through a configured NFS server in that VM. If you perform the backup against volumes that directly attach to HANA Large Instance units, copy the backups to an Azure storage account. Do this after you set up an Azure VM that exports NFS shares that are based on Azure Storage. You can also use either an Azure Backup vault or Azure cold storage. https://docs.microsoft.com/en-us/azure/virtual-machines/workloads/sap/hana-backup-restore

Ans - No. HANA HLI cannot be backed up using Azure backint and put into Azure Recovery service vault. Disk backup and storage snapshots are supported for HANA HLI.
