Double your backup-speed or even more

You have a Hyper-V server A
A has DAS containing the VMs (No iSCSI/SAN/etc.)
A has 4 NICs
- 2 are Dynamic Windows Team for Mgt/VM traffic
- 2 are single-NIC for SMB3 Multichannel purposed for Veeam traffic

You have a V&R Server B
B has DAS containg the local Repository
B has 4 NICs
- 2 are Dynamic Windows Team for Mgt traffic
- 2 are single-NIC for SMB3 Multichannel purposed for Veeam traffic

If you setup Veeam the "normal" way,
(eg. Local Repository points to a folder on a local drive on Server B
and Server A doesn't have VSS HW providers thus can only be backed up "on-Host")
Veeam will use the Teams (And those, if switch-independant, mean 1Gb max. from A to B)

If you use the Options->Network Traffic->Networks option to set both SMB-NIC subnets as default, Veeam will still only use 1 NIC

If you setup B as follows:
Create a SMB-share to the local Repository. Remove and re-add (If default, Add a Local 2, switch in Jobs, remove Local and rename Local 2 to Local)
the Local Repository as CIFS/SMB Server, reference the share. Also set preferred networks to both SMB-NIC subnets.
A will now backup to B using both SMB NICs due to Windows SMB Multichannel. This nearly doubles backup-speed and halves backup-time !
Imagine if you have 8 NICs and only use 2 for teams ! You could use 6 for Veeam traffic. Hope your local DAS can keep up !
