[ExchangeList] Re: exchange 2007 CCr and error checking

The replication is managed via transaction logs, not via direct database repl, which prevents corruption as you describe - so (mostly) no worries there.  of course, if something somehow corrupts one of the DBs due to content in a transaction log, chances are it will replicate over.  It's not true database clustering in the traditional sense.

See this article for some detail.

Hope that helps!

Hi Guys,
 
I am a bit new to this and just need  a bit more information on how ccr works, especially with error checking.
 
My understanding (and I may be wrong) is that with CCR the nodes are not required to have a shared storage subsystem. So which means each node keeps a copy of the exchange DB. My question is how is error checking done? if node2 takes a copy of node1's db, surely that could lead to node1 actually corrupting node2, or am i missing something. Also is it still possible to have the shared subsystem configuration, as I am just testing things out in my Lab.
 
 
Thanks
