 Once you make sure VirtualBOX 1 and VirtualBox 2 are communicating, you can backup the image and files from one VirtualBox to VHD of the other VirtualBox using the network. On my case I used CNT_Ente machine as a VirtualBox 2 and CNT_VB1 machine as a VirtualBox 1 which is the machine the VHD attached. On VirtualBox 1 (CNT_VB1) attach the VHD to do that go to - Start >> Right click Computer >> Manage >> Disk Management >> right click Disk management >> select Attach VHD >> Browse and locate your VHD (C:\VHDs\myvhd.vhd) >> then click Ok.

For the VHD to be accesed by other machines in the network. Computer >> Right click Virtual Hard Disk (myvhd(H:)) >> Properties >> select sharing tab >> In Advanced sharing >> Mark share this folder. 
 Then click Permissions under Advaned sharing>> under permissions - Allow Full control, change and read.


On VirtualBox 2 (CNT_Ente) to start the backup go to: Start >> Control Panel >> Under System and Security click Backup your computer >> Browse and select a network location. You need to provied username and password of VirtualBox 1. You can Set up Backup or backup a system image 
Select the network location that you are going to save the backup. To backup system image -
Select Create a system image >> On a network location Browse and select VHD (\\Cnt_vb1-pc\h\) >> Then click OK >>Confirm your backup setting and press Next >> press Start backup. This will take several minits.
