restoring data from NTBackup (exchange storage group backup)

I'm going through the process of restoring data from an Windows Windows backup in order to recover deleted emails. I'm going to use the "Recovery Storage Group" feature. My concern is the restoring of the backup to the server, via windows Backup. How do I know that that even after the Recovery Storage Group is created in Exchange, that the Windows backup utility is going to restore the backup to that Storage Group, and not the main storage group? I don't want to wipe out the existing data. The Windows Backup utility only specifies what server to restore to, and the location of log files/patches. Please advise. Thank you very much.

Hi,

No need to worry, the restore will go to the database only when you enable the option below,
 "This database can be overwritten by a restore" option in the database tab of mailbox database properties. ensure that this option is not selected.

You may proceed by creating RSG and restoring the data.

Thank you Praveen. Will the data be available after the restore, so that I can then attach it to the Recovery Storage Group?

You have to first create RSG,
then create the Recovery database, initiate the restore. The data will directly restore to the Recovery mailbox database, not to the original database :)

may this link help you in doing the task

I've looked into the website that you suggested petri.co.il ..... And the one thing that it explains, that I'm not seeing on my side of things is within NTBackup. "Open NTBACKUP, and then select the Restore and Manage Media tab.  Now, expand of the media containing the backup that you want to restore, choose your target storage group".
When I go to that part of NTBackup, I only see "Resore Files to: Original location". And it's grayed out. So I can't change it.

The restore went through successfully, but nothing was put in the mail store within the RSG. The mail store within it was created when I chose "Add Database to Recover" (after creating the RSG). I then selected the only option there, the main mail store. This is only a connection to the main store, right? Should this one's database property "This database can be overwritten by a restore" be left unchecked too? If I check the box for that option, will it just allow that data store in the RSG to be overwritten by the restore? Is that why nothing was put in that mail store? If I have to check this box, will the restore affect the main mail store at this point?

I tried allowing the mail store in the RSG to be able to be overwritten by a restore, but that didn't get me anywhere. The restore still goes through. But I don't see the restored messages anywhere.

Hope you have selected the right database when you created the recovery database. You need to allow the recovery database to overwrite by a restore option. When you select the database from the ntbackup restore selection, the restore will verify if it has an recovery database has created for the same database or not. The recovery database association is important.

Also verify if your backup is successful, any issue in the backup can lead to this issue.

Also see this - http://www.outlookexchange.com/articles/HenrikWalther/RSG.asp

If you do mistake anywhere, the restore will not be successful. :)

Should I delete the recovery database, RSG, and retry? Although there's only one database to select from up on creation. I can't see where else an error would be.

When I go to the location of the "system path location" of the RSG, I see an .edb and .stm file that is around the size I would expect to see. Why isn't this data seen within the RSG store? Is it because I have to mount the store within the RSG? If so, do I disregard the MS checkpoint warning I get when I choose mount store?

Yes, you will have to mount the store inside RSG.  the process is clearly explained in the below article from Microsoft.

http://technet.microsoft.com/en-us/library/aa998106%28EXCHG.65%29.aspx

Mention the error you receive when you try to mount the database, you may have to do the hard repair manually(every steps are available on above link).
