Storage Pool for Individual Backups not working right

I have started to use the new feature where you can designate a specific storage pool for each backup job. The backup completed, I was able to backup an offsite server to a disk drive attached to that server inside the same network.

However, there is a problem... From my VMware host I could see that the network traffic for the backup was actually coming through the WAN back to my backup server's network instead of staying within the network local to that offsite server. Essentially, the data for the backup was having to travel through the Wide Area Network twice. Once, coming back to the Vembu Backup Server and then second, traveling back out to the offsite server disk drive.

Am I doing something wrong? Can this be fixed?

Vembu BDR supports image-level backups of virtual machines hosted on an ESX/ESXi host with SAN or iSCSI storage. Virtual machines can read data directly from shared VMFS LUNs, so backups are very efficient and do not put significant load on production ESX/ESXi hosts or the virtual network.

To know more about the transport modes in Vmware backup please refer the below blog


Normally if the Vmware host and Vembu BDR server reside in the same network then the LAN transport mode will be used for backup.From your post we understand that your backup server is in offsite location so the backup will need WAN setup to transfer the data.

Vembu support called me with an answer. This cannot be done the way I want it to be. If I only have one Backup Server, then all backup traffic will need to come through that server before being saved to the storage device. The only way to do what I am wanting would be to set up a backup server in every location. If the storage device is local to the Backup Server then the traffic will not need to traverse the Wide Area Network.
