I use DPM 2012 to protect my Exchange 2010 DAG (SP3 UR6). I do an Express Full once per 24 hours on each database (no incrementals or anything like that). I have a Recovery database on one of my mailbox servers, but am trying to determine how to size it.
Does the recovery database need to be just as large as the largest database (the largest database will never get more than 1TB in size) OR do I also need to factor in the size of the Log partition as well? For instance, I have a database lun of 1TB and a corresponding database log lun of 500GB, and they will never get bigger.....so does my recovery db lun need to be 1TB or 1.5TB (to include log files)? I think since I just do Express Full backups that all I will need is 1TB since it would just restore the database.
