Quickstart: Restore SAP HANA System Replication on Azure VMs using Azure CLI

Article
06/18/2024

This quickstart describes how to restore SAP HANA System Replication (HSR) using Azure CLI.

SAP HANA databases are critical workloads that require a low recovery-point objective (RPO) and long-term retention. This article describes how you can back up SAP HANA databases that are running on Azure virtual machines (VMs) to an Azure Backup Recovery Services vault by using Azure Backup.

Note

Original Location Recovery (OLR) is currently not supported for HSR.
Restore to HSR instance isn't supported. However, restore only to HANA instance is supported.

Prerequisites

Before you restore from the HSR database backups, review the supported configurations and scenarios, see.

View the restore points for a protected database

Before you restore the database, view the available restore points of the protected database by running the following command:

az backup recoverypoint list --resource-group hanarghsr2 --vault-name hanavault10 --container-name "hanahsrcontainer;hsrtestps2" --item-name "saphanadatabase;hsrtestpradeep2;db1" --output table

abc@Azure:~$ az backup recoverypoint list --resource-group hanarghsr2 --vault-name hanavault10 --container-name "hanahsrcontainer;hsrtestps2" --item-name "saphanadatabase;hsrtestps2;db1" --output table

The list of recovery points will look as follows:

Name                       Time                              BackupManagementType    Item Name                            RecoveryPointType

arvind@Azure:~$

Note

If the command fails to extract the backup management type, check if the container name specified is complete or try using container friendly name instead.

Restore to an alternate location

To restore the database using Alternate Location Restore (ALR), run the following command:

az backup recoveryconfig show --resource-group hanarghsr2 --vault-name hanavault10 --container-name "hanahsrcontainer;hsrtestps2" --item-name "saphanadatabase;hsrtestps2;db1" --restore-mode AlternateWorkloadRestore --log-point-in-time 04-05-2023-08:27:54 --target-item-name restored_DB_pradeep  --target-server-name hsr-primary --target-container-name  hsr-primary --target-server-type HANAInstance --backup-management-type AzureWorkload --workload-type SAPHANA --output json > recoveryInput.json

 arvind@Azure:~$ cat recoveryInput.json
{
  "alternate_directory_paths": null,
  "container_id": "/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/hanarghsr2/providers/Microsoft.RecoveryServices/vaults/hanavault10/backupFabrics/Azure/protectionContainers/vmappcontainer;compute;hanarghsr2;hsr-primary",

  "database_name": "ARV/restored_DB_p2",
  "filepath": null,

  "item_uri": "SAPHanaDatabase;hsrtestps2;db1",
  "log_point_in_time": "04-05-2023-08:27:54",
  "recovery_mode": null,
  "recovery_point_id": "DefaultRangeRecoveryPoint",
  "restore_mode": "AlternateLocation",
  "source_resource_id": null,
  "workload_type": "SAPHanaDatabase"
}
arvind@Azure:~$

az backup restore restore-azurewl --resource-group hanarghsr2 --vault-name hanavault10 --recovery-config recoveryInput.json --output table

Restore as files:

To restore the database as files, run the following command:

az backup recoveryconfig show --resource-group hanarghsr2 \
    --vault-name hanavault10 \
    --container-name "hanahsrcontainer;hsrtestps2" \
    --item-name "saphanadatabase;hsrtestps2;arv" \
    --restore-mode RestoreAsFiles \
    --log-point-in-time 18-04-2023-09:53:00 \
    --rp-name DefaultRangeRecoveryPoint \
    --target-container-name "VMAppContainer;Compute;hanarghsr2;hsr-primary"  \
    --filepath /home/abc \
    --output json
	
	az backup restore restore-azurewl --resource-group hanarghsr2 \
    --vault-name hanavault10 \
    --restore-config recoveryconfig.json \
    --output json

az backup recoveryconfig show --resource-group hanarghsr2     --vault-name hanavault10     --container-name "hanahsrcontainer;hsrtestps2"     --item-name "saphanadatabase;hsrtestps2;arv"     --restore-mode RestoreAsFiles     --log-point-in-time 18-04-2023-09:53:00     --rp-name DefaultRangeRecoveryPoint     --target-container-name "VMAppContainer;Compute;hanarghsr2;hsr-primary"      --filepath /home/abc     --output json  > recoveryconfig.json
