Is it possible to back up VM in a remote site without network traffic between sites (only one VC in HQ)?
We are planing to start additional office in a remote site. We have HQ with 2 esxi 5.0 + vcenter + vdr and planing to open additional site with 2 esxi + vdr.
Well,
if you install a second vdr-appliance in the second site and choose a backup store which is also located at the second site, the backup-traffic will stay there. The only traffic between the two sites will be the configuration commands send to the VMs to be backed up, like take snapshot, clone, etc.

Would my VDR on a remote site connect to remote site hosts directly?
How would routing work? VDR ip would connect to remote site host's vkernel ip?
As I understand, VDR would make a snapshot and connect vmdk to itself (no huge traffic to HQ)?
The VDR-Appliance would be hosted on one of the new ESXi servers at the remote site. It sends commands to the vCenter, like "take snapshot from VM". Now the VDR-Appliance mounts the vmdk of that VM and writes the backup to its chosen backup datastore. The only network traffic to the HQ will be this tiny snapshot-commands to the vCenter. How much network traffic the backup generates at your remote site depends on what your backup datastore for the VDR-Appliance is ( NFS-share, "local" vmdk on FC SAN, etc.)

Hi if you are taking backup in remote location definitly traffic will increase , to reduce traffic you have to configure what backup data will contain ( mean full backup or only registry )

What do you mean? To backup only few VM?
I thought that the question was almost answered, becouse as described Tim, the backup traffic stays inside host-vdr-datastore, only signalling traffice to VC.
I think he meant the traffic would increase if you backup the remote site with your VDR-Appliance at the HQ, which is correct of course. But since you install a second VDR-Appliance at the remote site this won't happen :smileywink:

Thank you all for your explanation.
