Exchange Restore Error V-79-57344-959

I have Backup Exec 15 on WinServer 2012 R2, running Exchange2010 on VMWare 5.5

I have 1 CAS and and a DAG on 2 seperate servers (3 servers in total)

I'm trying to restore email I get this error.  V-79-57344-959 - Unable to open the item Database - skipped.

I read that I need to install agent on CAS to do install, what agent would that be, i cannot find any documentation for this.

This is a new install and it's a trial version. I find it reprehensible that Symanctec would not have any presale phone support for an enterprise product. I have vendors banging down my doors begging for business and offering any pre-sales support to evaluate if a product works well in my environment.
