 * Large volumes are currently not supported with Azure NetApp Files backup.
 * You can't create a large volume with application volume groups.
 * Currently, large volumes aren't suited for database (HANA, Oracle, SQL Server, etc.) data and log volumes. For database workloads requiring more than a single volume’s throughput limit, consider deploying multiple regular volumes. To optimize multiple volume deployments for databases, use [application volume groups](application-volume-group-concept.md).
