 You can run an on-demand backup using SAP HANA native clients to local file-system instead of Backint. Learn more how to [manage operations using SAP native clients](sap-hana-database-manage.md#manage-operations-using-sap-hana-native-clients).
 
+## Configure multistreaming data backups for higher throughput using Backint
+
+To configure multistreaming data backups, see the [SAP documentation](https://help.sap.com/docs/SAP_HANA_PLATFORM/6b94445c94ae495c83a19646e7c3fd56/18db704959a24809be8d01cc0a409681.html).

+### Support matrix
+
+- **Supported HANA versions**: SAP HANA 2.0 SP05 and prior.
+- **Parameters to enable SAP HANA settings for multistreaming**: 
+  - *parallel_data_backup_backint_channels*
+  - *data_backup_buffer_size (optional)*
+
+  >[!Note]
+  >By setting the above HANA parameters will lead to increased memory and CPU utilization. We recommend that you monitor the memory consumption and CPU utilization as overutilization might negatively impact the backup and other HANA operations.
+
+- **Backup performance for databases**: The performance gain will be more prominent for larger databases.
+
+- **Database size applicable for multistreaming**: The number of multistreaming channels applies to all data backups *larger than 128 GB*. Data backups smaller than 128 GB always use only one channel.
+
+- **Supported backup throughput**: Multistreaming currently supports the data backup throughput of up to *1.5 GBps*. Recovery throughput is slower than the backup throughput.
+
+- **VM configuration applicable for multistreaming**: To utilize the benefits of multistreaming, the VM needs to have a minimum configuration of *16 vCPUs* and *128 GB* of RAM.
+- **Limiting factors**: Throughput of *total disk LVM striping* and *VM network*, whichever hits first.
