![]() Learn more about backup and restore throughput performance.ĭetailed logs are written to the backup.log and backint.log files on the SAP HANA instance. Additionally, when you use firewall/NVA, the traffic to Microsoft Entra ID and Azure Backup Service will pass through the firewall/NVA and it doesn’t affect the overall backup performance.Īzure Backup attempts to achieve speeds up to 420 MB/sec for non-log backups and up to 100 MB/sec for log backups. ![]() Also, you can set up Virtual Network Service Endpoint or Private Endpoint to allow SAP HANA to send backup traffic directly to Recovery Services Vault / Azure Storage, skipping NVA/Azure Firewall. If you aren’t using firewall/NVA in your setup, then the backup stream is transferred over the Azure network to the Recovery Services vault / Azure Storage. To stream the backup data, Backint creates up to three pipes, which directly write to Recovery Services vault of Azure Backup. However, using uncached disks with M64Is can provide higher speeds. Premium SSD disks can provide optimal I/O throughput for the backup streaming operation. Once SAP HANA Backup Engine/Backint receives the backup request, it prepares the SAP HANA database for a backup by creating a save point, and moving data to underlying storage volumes.īackint then executes the read operation from the underlying data volumes – the index server and XS engine for the Tenant database and name server for the SYSTEMDB. The scheduled backups are managed by crontab entries created on the HANA VM, while the on-demand backups are directly triggered by the Azure Backup service. This section provides you with an understanding about the backup process of an HANA database running on an Azure VM. The backup is performed by streams generated by SAP HANA. To configure backup on the discovered databases, choose the required backup policy and enable backups.Īzure Backup for SAP HANA (a Backint certified solution) doesn't depend on the underlying disk or VM types. This plugin uses the Backup user created by the pre-registration script to perform all backup and restore operations. The Azure Backup service now installs the Azure Backup Plugin for HANA on the registered SAP HANA server. If you attempt to configure backup for SAP HANA databases without running this script, you might receive the error UserErrorHanaScriptNotRun. See the details about what the pre-registration script does. See the recommendation on how to set up Azure VMs running in SAP HANA with additional network components to use the backup offering. To enable the Azure Backup service to discover databases, you must run this preregistration script on the HANA server as a root user.Įnsure that the prerequisite to set up the right network connectivity is met. The Azure VM running an SAP HANA server is registered with the vault, and the databases to be backed up are discovered. This vault will be used to store the backups and recovery points created over time. To begin the backup process, create a Recovery Services vault in Azure. For a detailed understanding of the backup process, see the following process: See the high-level architecture of Azure Backup for SAP HANA databases. In the following sections you'll learn about the backup architecture of HANA databases in Azure Backup. ![]() It also enables Azure Backup to perform restores. This plugin connects with HANA Backint and helps the Azure Backup service to move data to the vault. ![]() To back up SAP HANA databases running on Azure VM, you need to allow the installation of the plugin (SAP HANA Backup agent) on the Azure VM. Learn more about Recovery Services vault. A vault is an online-storage entity in Azure that's used to store data, such as backup copies, recovery points, and backup policies. Where is the data backed up?Īzure Backup stores the backed-up data in Recovery Services vaults. Learn more about the added values that Azure Backup provides for SAP HANA. With this solution, you can seamlessly back up and restore SAP HANA databases running on Azure VMs and use the enterprise management capabilities that Azure Backup provides. This backup offering requires zero-infrastructure setup, thereby eliminating the need to deploy and manage backup-infrastructure.Īzure Backup is Backint certified by SAP, provides native backup support by using SAP HANA’s native APIs. How does Azure Backup work with SAP HANA databases?Īzure Backup provides a streaming backup solution to back up SAP HANA databases running on an Azure VM. This article describes the Azure Backup architecture components and processes. Azure Backup service allows you to back up data from SAP HANA databases in an application in consistent manner.
