Challenge
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.
Cause
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.
Solution
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 9.5.4.2753
-
Make sure no database backups are running for your SAP HANA server
-
Log in to server as root user
-
Download https://storage.veeam.com/Fix_168163_6a3408d4d4.zip archive containing the fix to SAP HANA server
-
Unpack it using the following command:
unzip Fix_168163_6a3408d4d4.zip
-
Verify checksums of the files using the following command:
md5sum -c MD5.txt
The result should be OK for each file
-
Perform the following commands
cp /opt/veeam/VeeamPluginforSAPHANA/hdbbackint /opt/veeam/VeeamPluginforSAPHANA/hdbbackint.bak cp /opt/veeam/VeeamPluginforSAPHANA/SapBackintManager /opt/veeam/VeeamPluginforSAPHANA/SapBackintManager.bak mv /opt/veeam/VeeamPluginforSAPHANA/hdbbackint /opt/veeam/VeeamPluginforSAPHANA/hdbbackint.orig mv /opt/veeam/VeeamPluginforSAPHANA/SapBackintManager /opt/veeam/VeeamPluginforSAPHANA/SapBackintManager.orig cp hdbbackint /opt/veeam/VeeamPluginforSAPHANA/ cp SapBackintManager /opt/veeam/VeeamPluginforSAPHANA/ chmod 755 /opt/veeam/VeeamPluginforSAPHANA/hdbbackint chmod 755 /opt/veeam/VeeamPluginforSAPHANA/SapBackintManager

Continue running backups as usual
