How long the consistency check takes is dependent on processor, memory, and disk speed. I’d let it run for at least an hour before I became concerned; and then I’d check perfmon/resmon before I killed it to see if it is still doing something…that is, establish a baseline and then compare against the baseline.
Doing a backup using WSB will not take down Exchange or related services. Regards, Michael B.

Based on my calculation, I should let the consistency check run for at least 20 minutes then. Since i'm new to WSB and Exch2k10 for that matter, I have to ask -- the backup process won't bring down access to Exchange or any related services before, during or after it's performed its business, right ? Not running DAG here yet. Thanks, On Wed, Jun 2, 2010 at 12:28 PM, Michael B. Smith <mich...@smithcons.com<mailto:mich...@smithcons.com>> wrote: How big is your exchange database? A consistency check on one of my client’s databases, 90 GB, takes about 50 minutes. The parameter you are referring to is primarily for controlling WHERE you take a backup in a DAG environment (passive, active, or both).

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.
