Hi @dika - not too familiar with SAP Hana plugin myself, but from the output of your error, I’d say you have some service account permission issue you’re using with the plugin. I’d also take a look at the logs on the VBR server in C:\ProgramData\Veeam\Backup , with the folder of the job name you’re having issue with to check if you can see anything more definitive/detailed what the issue may be.
If all else fails, you can certainly post a question in the forums, and/or open a case with Veeam Support.
