Backup Exec 2010 SP3 - Compatability with Exchange 2010 SP3

Hello,

I'm looking at the Backup exec 2010 R3 SCL. It states the it can support only Exchange 2010 SP2. Does the backup server itself need to be a 2008R2 system? I think I'm missing that part. Currently mine is 2003 SP2. Also, is there a possibe update to support Exchange 2010 SP3?

Thanks in advance for your help,

R
