Read/copy directly from backuptape

Is it possible to read/copy files directly from a backuptape? I have a problem with an deleted mailbox, which must be recovered. When that mailbox was deleted, the system only backupped the Information Store, instead of the mailboxes.
I know that you can copy the IS with Powercontrols, but it is to expensive right now (900dollars excl. agents (?) ).
So, I'm looking for a alternative solution. Or is it possible to read from the backuptape directly?

Backup system;
Powervault 122T (LTO2 tapes)
Veritas Backup Exec 9.0

Exchange 5.5
Watch Question

If you only backed up the Information Store, you will not be able to do a brick-level restore, to my knowledge.

I do not know as much about Exchange 5.5, but are you sure the user's box is completely deleted?

Is there any chance your users use Outlook 2003?  If so, often the PST file is still existent even when the server box is gone.  In that case, you can usually enter in recovery mode (or offline), "export" the PST to a file, then log back in Outlook into your "deleted profile," and import the PST.  This will put all of the e-mail back on the Exchange Server for you, if it is truly gone.


Yes, the mailbox is completely deleted.

There are tools (like Powercontrols) which can read/extract the mailboxes from a *.edb files (in this situation it is priv1.edb). The tool will export the mailbox to a *.PST file, wich I can open in outlook (2003). So, that's not a problem. The problem right now is that I want to copy the priv1.edb directly from the backuptape.
Is there a reason you want to copy it directly from the tape versus the way I just mentioned?  Would it not have the same effect?


Nope (sorry, forgot to answer on that question), I'd already look for an archive file (pst), but the one I found is very old and not usefull (only same old sended files where archived).
Can you still get into the mailbox in a cached version on the client's outlook?  Can you go offline or into recovery mode and see the messages still?


How can I start Outlook in recovery mode?

Setup another server, restore the information store to it and then use exmerge to extract the user or mailbox.

If you only want to restore the *.edb file do a file redirect and restore it someplace else.

From there you can do your mailbox recovery.

What backup program are you using?

Ooops I reread your post (stupid cold medicine).

You're using backupexec...just do a restore and redirect the file to someplace else.

Not the solution you were looking for? Getting a personalized solution is easy.

It's unfortunate but with Exchange 5.5 your options are VERY limited and to further your problem you only have a backup of the IS (which is all you need for a complete restore but in this situation doesn't help you at all). As far as I know rindi's suggestion is the only solution in this case.

Try using the Exchange Mailbox Recovery Wizard. If not, the other easiest way to go about it is to restore from tape, and use exmerge to make a .pst out of it.


Thanks guys!

I'll never knew I could restore a file on to another destination. From that destination I can rip the mailbox with Powercontrols (evaluation version) and export it to an PST file.


Ok, this wasn't the right solution. Because the backupped IS is not really a file, so my recent IS was overwritten (was not really a big problem, because I had a recent backup).. Have somebody another solution?
I don't understand your last comment.  Could you re-phrase?


I can't restore the Information Store to another location.
