Applications • Plugin backup to DataDomain - very high CPU consumption on gateway server

In a customer project the HANA plugin backups have to go to a DataDomain system (non-FC, setup according to Dell guidelines -> decompress before storing, etc.).

According to https://bp.veeam.com/vbr/2_Design_Struc ... e_Plugins/ one should size 1CPU/1GB RAM per enterprise plugin channel.

Our single Windows 2022 gateway VM has 12 vCPUs and 16GB RAM and even a single plugin job backing up a ~4TB HANA DB using 6 channels already uses >70% of the hosts CPU. With those 12 CPUs we should be able to accommodate 10x more channels (~60).

Any ideas why CPU usage is that high?
It prevents us from scaling the solution.

Thanks,
Mike
