My exchange 2010 server lost power before it was able to perform a clean shutdown and while coming back online some of the log files became corrupted. I've tried every safe-recovery option up my sleeve but finally decided to run the eseutil /p command and hope for the best.

my exchange data file is well over 500gb, about 540gb to be more exact and while I expected the process to take more than a few hours to complete, we're going hour 23 and we're at what I believe is the last step: Deleting MSsyLocales; I know after I run this process that I'm going to have to run a defragmentation and then finally an integrity check; but management is concerned about email being down for a full day. 

I'd like to sit down with management and give them a better idea of how long this process is going to take, and hoping that my math is wrong: It's processed about 14gb every 15 minutes during this step which would indicate i have another 9-ish hours to go. And then to run the defragmentation which research shows processes at about 3-5gb/h I'm looking at an additional 110hrs?! Please tell me my math is off.

Any reassurance that we're almost out of the woods would be greatly appreciated.

Hi..

Eseutil /p runs at the speed of approx 4-5GB per hour and you are saying you have more than 500GB. :O

It will take more than 5 days to perform the recovery operation. I think you should go for third party tool to perform the instant recoverry

Thanks

You can visit http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_28018373.html to know how to recover your damaged Exchange Server successfully.

You can use the New-MailboxRepairRequest cmdlet to detect and repair mailbox corruptions. Please refer to this technet resource to get more information in depth : https://technet.microsoft.com/en-us/library/ff625221%28v=exchg.141%29.aspx

If the issue still persist, you may try this automated solution too (http://www.exchangeserverrecovery.com/) that could be a good approach to repair exchange database and restore all the data back into previous used format.

Hi,

Based on my knowledge, eseutil /p runs at approximately 3 to 6 GB per hour, defragmentation takes 9 GB per hour is the speed at which the Eseutil utility runs. This number is only for reference. The exact number depends on your hardware and production environment.

And the Isinteg process after the repair runs at approximately 3 to 6 GB per hour. (These rates are average; performance may vary depending on how many passes the repair has to make on your database and the speed of the hardware.)

And don't forget 'Dial Tone recovery' as an option to get mail functioning with historical information later.
