No idea at this moment since we don't support WAN acceleration with VEB
. But it might be certainly something that we can debate on internally.
I do understand pretty much what you want to achieve. What I wonder now is if you can use VEB on the AD, file and print server... and use maybe a share on the file and print server as a target. Then deploy the WAN accelerator & repository role on one of those machines (file and print server again?) and use it in your backup copy job to the main office. I can't say I am completely sure, but I think it should work.
Dima? Does this sound like a potential solution?
