Dear support,

I am using Microsoft DPM 2010 for backing up my HyperV machines. DPM does only transfer the differences. Now i want to backup my virtual machines to another server with VPN (DPM 2010 does not backup to other server).
My question is: Does ViceVersa only sends the differences with a VSS copy of a hyperV disk?
Or does it sends the whole vhd everytime?

Please get back to me.

Dennis

Are you planning to use deltablock ? Because then it sends only the differences. Am i right?

Thank you.

Hello

yes, with that functionality it would send only the changes. How effective that is with a hyper-v machines needs to be analyzed. If the file changes a lot anyway in between replications, that would not speed up the copy at all, even make it slower.

thanks
