I just wanted some clarification on RSGs in Exchange 2007. I am building a CCR Exchange 2007 cluster to host my companys mailboxes, consolidating many sites into one. I also have a separate mailbox server for public folders and mailboxes.
I was planning to have a recovery storage group ready from the first day and was wondering if I needed one or two RSGs? I was planning to host one RSG on the mailbox/public folder server with enough disk space to host mailboxes if my CCR cluster blew up and I had to recover from backup. This would be ideal for due to storage requirements for an RSG on a CCR cluster would be double (disk space presented to both nodes)
Is my approach acceptable practice??
