Backup Exec 16 VSS issues with server 2012 R2

I have a new setup with Backup Exec 16 installed on Windows Server 2012 R2 64-bit. Mostly working fine with 2 virtual hosts and an exchange server, and speed is good. However, we also have a new file...

    For the 63TB issue you can create/adjust a registry key

    http://www.veritas.com/docs/000024505

    - however be aware that the 63TB is kind of a Microsoft recommended limit for VSS operations and as such using larger volumes and increasing this too far might introduce other issues (timeouts etc)

     

    Also be aware that the way you calculate 63TB might be at fault as the limit is 57.3TB if using by 1024 multipliers/divisors

    If it does not exist already you create it and as far as I know you do it on the server being backed up , however it won't harm to do it on both places.

Actually, that tech doc is a little unclear as to whether the registry entry needs to be created or changed on the BE server or the server being backed up. Could you confirm?
