Integrate incrementals from two different servers but same job fileset. Possible?

Hello,

The situation is the following:

1. Initial backup of a WAN client (Windows SBS 2008 / ~450 GB data in two volumes) was done using *Windows Image Backup* to an external HD.

2. Restored the WIB to a test virtual machine in the vSphere cluster.

3. FULL backup of D: and G: (450 GB data) to this virtual machine was done with BE 2012 (Windows Agent installed)

What I am trying to achieve here is the ability to *perform incremental* from FULL backup to the original WAN client using Backup Exec 2012.

I know Bacula can do it by simply redefining the name of the client to be backup but keeping the same fileset. Is there a similar approach or method with BE 2012?

Thanks in advance for your help.
