We are currently running exchange 2007 in a CCR cluster and will very shortly be going to exchange 2010 in a DAG. Currently we try to keep our DB's between 100 and 150 GB in case we need to recover/repair/etc
I am just looking for information on what you guys are trying to keep your DBs around. Looking at the MS documentation it says in a DAG the DB size can be up to 2TB to me that seems insane. I cant imagine repairing a 2TB database if you had an emergency.
