MS Exchange 2013 deployment using BE 2014 on Windows 2008 32bit

Hi,

We have the following :-

1. MS Exchange 2013 CU2 on Win 2012 Server STD (64 bit) as VM in VMware.

2. BE 2014 on Windows 2008 Std (32bit). in a physical server.

IS there going to be any challange to take backup and GRT restore

These Exchange server is on HA based Exchange 2013 (two server).

Thanks
