Re: Can not restore Exchange Storage Group

Nuevo,

Thanks for the quick response! In response to your questions,

- When I originally created the backup set, I remember selecting the entire
storage group. However, opening NTBackup and reloading the saved backup
selections, only the individual Storage Groups are selected. I re-selected
the Information Store and saved the backup selection again and then
re-opened it and found that NTBackup only seems to store the storage group
selections and not the top level Information Store. That being said, every
Storage Group in the organization is backed up.
- Yes, I restore to the same Exchange organization and server name
- I'm overwriting the existing db. I tried using an RSG, but found that it
wouldn't get me my Public Folder data back, so I abandoned that approach.
- If I run eseutil /cm in the recovery directory, it lists in the "Log files
range" section, all the log files I have in that directory. However, in
viewing the corresponding event log entry to a failed "eseutil /cc", I
notice that the event log entry reports that I need an log file which is
considerably smaller than what I have available (I require 28287 and it can
only find 28648).

Thanks again.

When you use NTBackup you are given the option to backup the Information
Store or individual dbs. What exactly are you backing up? When you restore
I assume you are restoring to the same Exchange org and same server name?
Are you restoring to an RSG or directly overwriting the db (this of course
assumes you created the storage groups and dbs to match your production
environment)? The different physical hardware is irrelevant other than the
partitions which should hopefully match the existing server. The first
error seems to indicate missing log files. You should check which log
files are being restored and how they correspond to the log file listed in
the restore.env file.

I'm attempting to test our data recovery procedures and part of that
process is to restore our Exchange Server 2003 organization. I've set up
a lab environment where I've successfully restored all our domain
controllers and our front-end Exchange Server. Unfortunately, I can't
seem to figure out how to restore our back-end mail server. When
restoring through NTBackup, the application reports that the restore
operation completes successfully, but the mailbox store never mounts.
Going through the event log, the last ESE error I see is a 454 error that
states "Information Store (3016) Restore0027: Database recovery/restore
failed with unexpected error -515". If I attempt to run essential
directly from the working directory NTBackup created with the command
"essential /cc", the operation fails with "Operation terminated with
error -543 (JET_errRequiredLogFilesMissing, The required log files for
recovery is missing.)". I've also tried to restore to a recovery storage
group, but I run into problems with the Storage Group's Public Folder
Store.

I can't figure out why the restore is failing. The system in the lab
environment is of a completely different hardware configuration (Virtual
Server 2005 VM) than what our production servers are running on - I don't
know if that makes a difference. Also, the original full backup that I'm
testing the restore from is a complete backup of the entire system, minus
the "Program Files\Exchsrvr\MDBDATA" directory. The way I'm
understanding the Microsoft Exchange Server backup documentation, if I'm
backing up the Exchange Server storage groups, the MDBDATA directory
should be excluded, or am I misunderstanding something? Can anybody
provide me with any pointers of things I could try?

Thanks.
