Backup Exec 2014 Vs MS-Exchange 2013

I would like to understand the BE-2014 version's technical limitations and/or points-to-be-considered for MS-Exchange 2013 backup/restore operations.

Example: 

1. Maximum backup size allowed per job, etc...
2. To back up Microsoft Exchange Server 2013, you must install Backup Exec on a Microsoft Windows 2008 R2 SP1 64-bit server or newer.
