When backing up a small (<128 GB) tenant/system DB of SAP HANA, the backup performance might be comparatively slower than a file based backup or using a different backup solution.
After several customers pointed out the performance degradation – compared to file based backups – the Veeam development team found a way to significantly reduce the overhead for single stream-backups which leads to higher performance and faster backup times. This also improves the use of multi-channel backups – as the number of channels can be significantly smaller.
There is a hotfix for the issue which improves backup performance and eliminates the overhead of backup operations. Follow the next steps to apply the hotfix.
Make sure the Veeam Backup and Replication server and Veeam Plug-in for SAP HANA have been upgraded to version 188.8.131.5253
Make sure no database backups are running for your SAP HANA server
