I have two physical servers :
1 : One Windows Server 2008 R2 with veeam 7.0 at our main site (let’s call it SRV-MAIN-VEEAM)
2 : One vSphere ESXi 5.0 with one VM (File server) and one VM (Veeam 7.0 server) at remote site. (SRV-BRANCH-HOST with SRV-BRANCH-FILES, SRV-BRANCH-VEEAM)
SRV-BRANCH-HOST has no vCenter (no cluster, just a standalone VMWare server).
My 2 sites are not linked by VPN. They have their own ISPs.
My goal : starting from SRV-MAIN-VEEAM, backup SRV-BRANCH-FILES.
I have a few hypothesis:
H1) is the SRV-MAIN-VEEAM which launches backup on the SRV-BRANCH-VEEAM ?
If H1) : does SRV-BRANCH-VEEAM push data (through WAN) to SRV-MAIN-VEEAM or is it the opposite ?
H2) Do I need to add SRV-BRANCH-VEEAM into SRV-MAIN-VEEAM or the opposite ? or both ?
H3) using creds : to specify creds, I still use {local_ip_server}\Administrator. Is that right ?
My tests :
- On SRV-MAIN-VEEAM, I added the remote SRV-BRANCH-VEEAM in “File => Microsoft Windows” item
- I open (output) following ports on main site firewall : 443, 902, 6060, 6064-6065, 2500-5000.
- I open (input) with NAT the same ports on the branch’s firewall. All ports are redirected to SRV-BRANCH-VEEAM except 443 and 902 to SRV-BRANCH-HOST
- Add SRV-BRANCH-VEEAM into “Backup Infrastructure => Wan accelerator” : success
- The opposite : still failing

Well, my questions :
Q1) do you have a scenario I can test with Veeam 7 between main site and branch using WAN Acceleration ?
Q2) which ones, in my hypothesis, are true/false ? Where am I wrong ?
Thank you for your answers.
