​edb corrupted repair RRS feed

  • Question

  • Hi))
    I have Exchange 2010 server that is being used to temporarily hold mailboxes. After a reboot the .edb file went from 276gb to 0kb. Of course i haven't even taken a full backup of the server yet. So now I have 276gb worth of log files but a 0kb EDB. I have tried using eseutil without any luck. Anyone have any suggestions?
    Thanks!

  • If eseutil is unable to recover the database in any way, then it is almost impossible to recover the database unless you have a back up for this db or you have a DAG in your environment with multiple copies of your database. In case you have configured DAG in your environment, then just reseed the database, otherwise, my friend, I am afraid that you are going to loose the data. Moreover, at last you can take the help from any third party tool to restore back you .edb file which is your last option in case you don' have any copes for it.

    1. So that type of issue is usually caused by some type of disk related issue therefore I would get that solved ASAP
    2. You can only roll logs into a DB that is in a dirty/backup state and even then the EDB will only accept logs from the last known log point.
    3. The ONLY way to recover that DB at this point would be A: if you had an offline backup of the EDB when it was first made or from some other point in time pre-disaster or B: if you can get the disk to a recovery specialist ALTHOUGH that may not work now that you have been attempting a repair because the more read/writes you do to that disk the less chance of recovery
    4. We have a team of experts that MIGHT be able to put it all back together for you, however it would be rather expensive to even attempt so consider the value and if interested in pursuing you can email me troyw at lucid8 dot com

    Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 --> 2013 with Lucid8's DigiScope

  • Misconfigured File system AV can also eat your database.  Ensure that all of the required exclusions are in place.

  • Hi neilgreory,

    Thank you for your question.

    We could refer to the following link to restore the database.

    https://technet.microsoft.com/en-us/library/bb124040(v=exchg.65).aspx

    After you restore it, we suggest you create backup policy to backup database.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,
