Harry, Make sure you have every patch for BE 2010 including HF 348518 (if running 64bit). There was a nasty bug that could cause a store corruption (ask me how I know). -Greg

I attempted to run a Windows Server Backup but the process was stuck on the Consistency check for Exchange.I waited for about 15 minutes until i cancelled the job to do some research. I followed the following steps here: http://technet.microsoft.com/en-us/library/dd876854.aspx and found the following forum post here: http://social.technet.microsoft.com/Forums/en/exchange2010/thread/88adaae6-2930-4785-a85f-9ae4d837eca2 In short, there is a post at the above forum that indicates to enable the following key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14\Replay\Parameters] Create new: "EnableVSSWriter"=dword:00000000 My question is, will the above key disable VSS functionality all together ? I plan on introducing Symantec BE 2010, will it also break BE's, or any VSS-reliant/aware app's ability to run a backup of Exchange? Thanks, Harry.
