Hello!
Consider there's a three-node DAG: Exch1, Exch2, Exch3. The default mailbox database on the first server (Exch1) has been removed - all mailboxes (including system ones) have been moved to the single database, for instance,Contoso db (on Exch1). Now this Contoso db is being replicated to the other DAG members - Exch1 and Exch2 - that DO HAVE their default databases (~Mailbox Database 0704..).
Q1: should these default databases (Exch2\Default and Exch3\Default) be added to the same (or to some other) DAG?
Q2: how must they be maintained (backed up...)?
I haven't found any information on it yet...
Thank you in advance,
Michael
