Dear all,

I have a problem here and believe that someone could help me get the issues resolved. Here is my scenario,

- I backed up "First Storage Group" that contains 'Mailbox Store' and 'Public Folder Store'.
- The full backup and the incremental backups were successful.
- I lost a specific mailbox. Hence I wanted to restore just that mailbox upto-date(as in the backup) and NOT ALL the mailboxes.
- Hence, I planned to restore the 'Mailbox Store' to the 'Recovery Storage Group' along with the log files(because numerous transactions are in those log files).
- When I restored the 'Mailbox Store' alone(as Public Folder Store cannot be restored to the 'Recovery Storage Group') along with the log files, I could see the following errors/failures.

Problem 1: The restored database 'Mailbox Store' was in 'Dirty Shutdown' state.

Problem 2: I am not able to replay the log files to the 'Recovery Storage Group' and when I manually try to do so, eseutil throws error and logs replay does not start.

I can resolve the 'Problem 1' by bringing the 'Mailbox Store' (now present in the Recovery Storage Group) to 'Clean Shutdwown' state by repairing the database. But I do not know how to replay the log files to the Recovery Storage Group. Can someone please help me on this issue? Is it possible to replay the log files to a Recovery Storage Group when restoring a 'Mailbox Store' alone and not the Public Folder Store? I suspect that the log file replay failure is due to the Public Folder Store only, because the log files would have got the transactions of the Public Folders too. Any way to recover the data from the log files also (by replaying them to the Recovery Storage Group)?

Hi all,

Adding to my previous post I just want to show you the results of some comamnds i ran to replay the log files. Any help is appreciated if there is a way to mount the database with all required logs replayed, without using '/p' switch(repair)!

The following are the command results of the steps i tried to restore the database to a Recovery Storage Group.

1) I ran the eseutil /mh command after restoring the exchange data to the RSG. please find the output.

2) The shutdown state is 'Dirty'. I do not know why the shutdown state is always 'Dirty' whenever i try to restore a database to RSG!. Since I did not choose 'Last Restore Set' while restoring the data, I tried to replay the log files manually. Please find the output of eseutil /cm command.

I am not sure what is the issue. Please advise. Is there any other method should i follow to restore a mailbox store to a Recovery Storage Group? hard recovery, soft recovery etc...! What step am I missing?

Many thanks,

Now, the problem is, Restored database to the RSG is in dirty shutdown. To acheive your goal, First, You have to convert the restored database to clean shutdown.

As per the error, the log files required to make the database to clean shutdown are from E00001CE.log - E00001D2.log.

Check whether you have the requried log files. if you have it specify the log file location while running the hard recovery

If you cannot find them or if you dont have anyways to make it clean shutdown, then my suggestion is to run the repair on the RSG database

I suggesting the repair, considering the fact that, there is no problem in the production and you are just trying to recover few emails out of some mailboxes

But the repair will not give you 100% guarntee that you will get all the emails back

Thanks Vijay. But I had all the log files intact. But all my attempts to restore to the Recovery Storage Group failed. I am aware of the hard repair option (eseutil /p) but if I have a huge mail transactions in the log files itself, repairing the database would be a loss of hundreds of mails. Only so I am looking for a way to replay the log files to the Recovery Storage Group. Are the steps I have followed correct?

Thanks for your time,

Did you try running the hard recovery by mentioning the log file location with the relavant switch?

nesanjoseph · Joined: 01 Jun 2009 Posts: 15

Yes. I ran eseutil /cc from the log file location. The output was like one I have posted in my second post in this thread. You can see the output and suggest me a solution. Thank you very much.

Thanks,

ok. K check the health of the log file from E00001CE.log - E00001D2.log

To know how to check the health of the log files, check the following link
http://technet.microsoft.com/en-us/library/aa996238(EXCHG.65).aspx

if the health is bad then there is no other option except to repair the database.

Sad

with regards,
Vijay
