Can exchange clustering prevent against full database corruption? I'm really curious about this because if the exchange database is on a SAN, in the case of corruption, clustering will not work at all because the exchange server will failover to an existing corrupted exchange database. Please let me know. Donny
No. Frequent backups and replication to secondary storage protect against database corruption. In the event of corruption you would restore and reply the logs.

What kind of replication can do this? Do you know of any high end product which is very capable ot doing this? Please recommend some to me.

hi donny! you can do it with products from neverfail, for example. you find them under www.neverfailgroup.com -- Gerald Aigenbauer http://www.ntc.at "donny" schrieb im Newsbeitrag news:6C67008E-0945-4D7A-A007-C165EDB48713@microsoft.com... > What kind of replication can do this?

Only you can prevent forest fires, er, I mean database corruption. Backup and replication are the key here. Clustering makes the corrupted database Highly Available. Cheers, Rodney R.

Your storage vendor would be you best bet if you want to do it on the backend storage. For NetApp, that means Snapmirror - either synchronous or "asynchronous" replication. EMC and HP have replication products, but you would need to consult with them for specifics. There are host based replication products as well, I believe Neverfail was already mentioned and then there's the NSI stuff and many others as well. Whatever you choose, make sure it's supportable under KB.895847 for replication of live data. If you are replicating snapshots as Snapmirror "asynchronous" replication does (not live data), then kb.822896 - specificly the requirements for checking snapshot consistency before mounting the databases.
