Restoring an Exchange 2007 mailbox from a StorageCraft ShadowProtect backup
Posted on 2012-12-27
My company needs to restore an individuals mailbox. It is believed that they deleted some important emails right before leaving the company. I have a backup of my exchange 2007 server using StorageCraft ShadowProtect Server Edition version 3.5.2.5266. I can mount my backup from the date specified and see my mailbox database.edb and the logs folder. I have created a recovery storage group on the exchange server and copied the .edb file and the logs into the RSG folders but I can't get the database to mount, the database is "dirty" even after running eseutil. There is also a log signature discrepancy error. Any direction on this matter is appreciated.

Which eseutil commands you run? did you run eseutil /r or eseutil /p?
What is the database size ?
Confirmed if the backup image you choosed was created by vssaware backup.
Trying using a vss aware backup image.
Run eseutil /mh against the db you recovered from the backup and check if it shows any log required status, if yes then copy the logs from the backup including the one's which are showing in required status and run soft recovery.
If you dont have the logs(probably due to circular logging) then you will have to run eseutil/p , eseutil /d against the database and then you will have to mount it in RSG.
Confirm if Ontrack email recovery tool is provided with your backup solution.

What is the details of eseutil /mh ?
Is the logs required in location ?
Did you try to run eseutil /cc to bring the DB into clean shutdown ?

I have tried to repair this about 6 times at this point, should I start fresh from my backup again? Also the exchange environment is very critical, I cant do anything that is going to bring the live database down.
the database doesn't required any logs.
Run eseutil /p manually against this db, then run eseutil /mh and check if it still shows in dirty shutdown. in that case you will have to mount another image and use db from it.

leaving it in RSG folder is fine. If you are repairing it in RSG folder itself then after the eseutil /p complets you will have to remove all the log files from the RSG folder(They got created when you attempted to mount db in RSG earlier).
