Backup Exec 2014 - Excessive WAN Usage to vCenter

Hi,

We have a central vCenter with 3 locations connected across a WAN 10Mbits/sec.

After switching to BE2014 we have found out that the network is bottlnecking while the Backup are running.

I'm seing  about 600MBytes of data within 60 mins.

We backup in SAN mode and BE & SAN are on the same subnet.

From what I know, only API calls are supposed to go through vCenter.

Any idea on how to fix this?
