my colleague and friend Tom Sightler created an toolset to backup SAP HANA with Veeam Backup & Replication. He documented everything in the Veeam Forum:
Basically it follows the same way that storage systems like NetApp use for Backup of HANA. You implement in Veeam Pre and Post Scripts that makes HANA aware of the Veeam Backups. As well Logfile Handling is included (how many backup data do you want to keep on HANA system itself?).
In case of a DB restore, you go to HANA Studio and can access the backup data on HANA system directly. If you need older versions you can restore them with Veeam File Level Recovery Wizard or more comfortable with the Veeam Enterprise Manager File Restore (Self Services) and hit the rescann button at HANA Studio restore wizard. They are detected and you can proceed with the restore.
