Elan,
I know that you cant backup an SCR. And that when you do /recoverCMS you
would have a CCR clus config and you can then backup that CCR Active node.
But my other question was regarding having a single SCR box in db
portability scenario, which has no CMS/passive node installed on it. Now in
that scenario, if the primary site goes down and you bring the SCR box
online, can you perform backups from that box at DR site? at this point its
is no longer an SCR Target, its a mbx server.
Thanks.
