PowerProtect Data Manager 19.15 SAP HANA User Guide

Enable multi-stream backups for SAP HANA protection policy

To enable multi-stream SAP HANA backups for a centralized protection policy, you can set the parallelism value in the PowerProtect Data Manager UI. The parallelism value controls the number of parallel streams that the SAP HANA application agent uses to write the backup data to protection storage.

Use the following guidelines to set the parallelism value in the PowerProtect Data Manager UI:

• Set the parallelism to a value that is equal to or very close to the parallel_data_backup_backint_channels parameter setting. When the two settings are equal or almost equal, the SAP HANA application agent can take full advantage of the parallelism provided by SAP HANA.
• Set the parallelism to a value that is not more than the maximum number of connections provided by protection storage.
• Set the parallelism to a value that is at least 3 less than the maximum number of connections provided by protection storage. Reserve 3 connections for the log backups. For example, when protection storage can provide a maximum of 10 connections, set the parallelism value to 7 (10 minus 3).

In the PowerProtect Data Manager UI, perform the following steps to set the parallelism for multi-stream backups:

1. Select Infrastructure > Assets > SAP HANA.
2. Select the SAP HANA asset.
3. Select More Actions > Set Stream Count.
4. Set the stream count for each backup level as a value between 1 and 28 in the Full, Differential, and Incremental fields.
5. Click Save.
