How to fix corrupt Exchange File

Posted on 2006-03-20

I am running SBS2003 and just installed Veritas Backup Exec. When backing up Exchange, I receive an error message stating that one of the files is corrupt.

All my users have no problems (yet?) with Exchange, so I have no idea how to resolve the corrupt file issue.

Here is the log:

    That is what happens when you do a brick level (mailboxes) backup. It will be a single email message causing that problem and it will only get worse.

    It isn't really a corrupt file. It is a message that Backup Exec cannot read. Most of the time a spam message. Spammers use all sorts of tricks to get their messages through the filters and this often causes a problem for applications that try to then read those messages.

    The only sure fire way to avoid those messages is to stop doing a brick level backup.
    Instead do just information store backups. Turn up the deleted item retention and mailbox recovery times and you will very rarely have to do a restore.

    When you do, use a feature of Exchange 2003 called Recovery Storage Group which you can quickly restore the data that you need.

    Many thanks.  So I should just backup the information store, which I assume includes messages in a proprietary form; and don't back up the messages.?

    Just backup the store - nothing else.
    Mailbox backup is close to useless - it will be no good to you in a disaster recovery scenario. I haven't done a mailbox backup for many years.
