Exchange 2003 Backup Problems

SBS 2003 with Exchange 2003

Backup Exec 2010

Exchange db size = about 4.8GB (the sum of the 2 priv1 files)

The Backup is consistently failing on the Exchange db.  I made a job that only does the exchange db and nothing else.  Still fails

But it backups 4.9GB of data

Backup exec errors:


V-79-57344-65146 - An error occurred while accessing Microsoft Exchange Server. Check the application event log on the Exchange Server for more details.

V-79-57344-65146 - An error occurred while accessing Microsoft Exchange Server. Check the application event log on the Exchange Server for more details.

WARNING: "\\server name\Microsoft Information Store\First Storage Group\Mailbox Store (server name)" is a corrupt file. This file cannot verify.


Is my db really corrupt?  Or is this Backup Exec being dumb?

If your exchange is running without any abnormalities otherwise i'd say your information store is probably fine. If the IS is broken, you'd find a bunch of events springing up telling you about it.

The problem you're referring to with Backup Exec is a recognised one. Take a look at this link for more information:-

Nice one.  It does seem that they have AV on the server.  i will disable and see if that helps.

Exchange aware Antivirus can be cause of problem, disable Antivirus and restart MSExchangeIS Service and check  the backup

To check whether Exchange-aware AV is enabled. Check this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSExchangeIS\VirusScan

If the "Enabled" value is set to 1, then Exchange-aware AV is enabled.

Change 1 to 0 to disable Exchange aware AV.

Also exclude the folders where database and logs are located  in Antivirus and then try taking backup

I made sure the AV was not scanning the Exchange db and restarted the info store.  But it still failed.

Backup Exec errors:

Backup- \\Server\Microsoft Information Store\First Storage GroupV-79-57344-65146 - An error occurred while accessing Microsoft Exchange Server. Check the application event log on the Exchange Server for more details.


WARNING: "\\Server\Microsoft Information Store\First Storage Group\Mailbox Store (Server)" is a corrupt file. This file cannot verify.



The registry on the above comment is currently set to 1.  I will change to 0 and restart store and see if that helps.
