Backup I/O control specification

[Yukinobu]

When we enable backup i/o control, where Veeam refer?
A ESXi metric running Proxy VM(HotAdd) or a ESXi running the backup target VM?

Are the specifications different depending on the difference in transfer mode?
Would you tell me the detailed specifications?

[Gostev]

Veeam refers to the ESXi running the backup target VM, and there's no difference depending on transfer mode.
