My setup is as follows:
HQ with 2 HyperV servers in cluster connected to SAN with SAS controllers.
Branch Office with Windows 2008R2 server, with 9Tb internal sata drive.
I want to minimise the time it takes to make a backup.
Incrementals are done in 6-8 hours over the WAN to CIFS share.
Specificly it takes "forever" to make a full synthetic backup on a remote CIFS share. I reached 14% in 50+ hours

I just want to be sure before I buy a server for the branchoffice.
As far as I can understand, I need to configure the backup repository on the branch office server to use vPower.
Im confused though, because as far as I understand, vPower is a VWWare technology?
Is it not possible with HyperV to have a proxy in branch office to do all the calculations and read/writes?
