Backup Exec (10.1 at least) has an annoying (and undocumented) bug when it comes to restoring to an Exchange 2003 Recovery Storage Group. When you go to restore a mail store to a recovery storage group, BE goes along for a couple minutes and then fails with error "V-79-57344-65280 - Unable to restore the selected Microsoft Exchange database 'MailStoreNameHere' because it is currently mounted. Use the Exchange System Manager to dismount it, and then retry the job.". The whole point of the recovery storage group is to restore user data without dismounting the production store, so this doesn't make a whole lot of sense. Recovery Storage Groups are a feature that is transparent to the backup/restore program. Exchange automatically redirects the restore to the recovery storage group as part of the existing APIs.
Apparently the issue is that Backup Exec is doing a query to Active Directory to determine whether the store is mounted, and of course it is. There is a registry key which can be set to tell Backup Exec to ignore the results of this query. To make this change create the following registry value (DWORD) on the Backup Exec server and the Exchange server:
HKLM\Software\Veritas\BackupExec\Engine\ese
name = "ignore mount state"
value = DWORD(1)

Friday, November 17 2006 4:00 AM by AlanThe fix worked for me for a full restore of DBs after a server crash. Like Jeff I only applied to the BE server at first. After calling Symantec and applying the fix to the Exchange server the restore (and automatic roll forward) worked perfectly.
Result - happy(ish) customer.
Lesson 2 - Always RAID1 your tranaction logs and RAID5 your edbs/stms, backup correctly and it actually works ;-)
Cheers Brian if I had read the blog correctly it wold have saved me a couple of hours in the early hours!!

Unfortunately the fix didn't work for me. I have a feeling the snapshot used MS VSS which looks to be the problem.
The error is shown below. I checked the KB's and ran all the tests with no errors. your help would be appreciated.
Writer Name: Exchange Server, Writer ID: {76FE1AC4-15F7-4BCD-987E-8E1ACB462FB7}, Last error: 0x800423f3, State: 0013. Consult your Microsoft documentation for details. Check the Windows Event Viewer for corresponding application or system errors.
V-79-57344-65233 - A failure occurred querying the Writer status.

Thursday, April 12 2007 8:23 PM by AsafExcellent Find - We've only recently come into this problem and found that we could easily restore our Storage Group in the first IS, but when it came to restoring any other SG's from different IS's the problem showed up (we've just never had to restore for any other IS before).
Lucky we didn't wait for Veritas/Symantec to get back to us - it's been a week with no word from them...

apparantly the vss writer is switched off by default and needs to be switched on for image restore (Exchange 2003) to work. This is for Windows Small Buiness Server but its prob the same for 2003 server as the platform is the same. back up exec v11d has notes on this problem
#8 re: Backup Exec Exchange 2003 Bug Workaround
Wednesday, May 23 2007 7:23 AM by Rosario CarcòI ran into the same problem after upgrading Backup Exec from 9.x to 10.0 - The upgrade was necessary because of a new LTO library we bought. But a colleque forgot to upgrade the remote agents so restoring to the RSG continued to work fine. After I upgraded the remote agents to 10 I got the error regarding mounted stores.
I am not sure whether modifying the registry is too risky. Does anyone know whether Symantec corrected the bug?
Thanks, Rosario
#9 re: Backup Exec Exchange 2003 Bug Workaround
Monday, June 11 2007 2:23 AM by Ran HooperDidn't work for me on 9.1 Backup Exec.
I was, however trying to restore into a new domain/server (SBS 2k3). I suspect this was part of my problem with it not working.
After screwing around with options, reg hax etc. for a couple of hours
I ended up copying the files over manually and using legacydn to hack it into mounting. Created some users, attached the old mailboxes and made some PST's - all is good.
#10 re: Backup Exec Exchange 2003 Bug Workaround
Monday, April 21 2008 4:07 PM by John V.So when I add the reg entries to both servers, it will restore to the "Recovery" storage group, correct?
#11 re: Backup Exec Exchange 2003 Bug Workaround
Friday, August 22 2008 8:45 AM by Aleksander GodlewskiYes, its working correct (on my v12)

Wednesday, December 24 2008 8:37 AM by Exch2003-BE11dWorked great with Backup Exec 11d and 2003 Enterprise server.
Here is the updated key for it:
[HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec For Windows\Backup Exec\Engine\ESE]
"Ignore Mount State"=dword:00000001
Thanks!

Tuesday, April 21 2009 10:51 AM by Mark GouldI think the word here is saviour.
Just remember to change BOTH the backup exec soyurce machine and the remote machine.
The tip also applies if you are using Ontrack PowerControls Extract wizard or similar

Will Symantec ever fix this problem?
(it seems, that they test the software only with one storagegroup - but maybe more than one SG is a "unusual" configuration *lol*)

This fix worked for me. I couldnt find this fix documented anywhere on the Veritas support site or anywhere else for that matter. I tried updating Veritas 10d to SP2 first but that did nto fix the problem.
You must add the registry key to both servers like the post says. I missed that at first and only applied it to the BE server. It worked after I applied to the Exchange server and restarted the BE Remote service.
Thanks for the post!!!!!
