I believe I am having the same issue.  When doing an Exchange Mailbox backup I recieve the following error.

 

I would like to open a support case for this but I am having the hardest time trying to navigate the website.  I have a support contract and I can't seem to figure out how to use it.  In my opinion this site sucks. 

 

When trying to open and email support case I get redirected to here only to find out that that last time this thread was updated was in November of last year and still has not resolution.  Is anyone out there?

Being able to restore individual exchange items aka GRT (granular restore tech.) is only supported on backup to disk folders, not tape drives.  Which of course symantec is quite misleading with their advertising and neglect to mention this small insignificant detail.  do a search on this forum for "GRT"  and you will see that their supposedlly wonderful granular restore technology is practically an alpha or early beta version at best.  I had some limited success backing up exchange to disk and then running another job to backup that folder to tape, but then I ran into GRT not following overwrite protection settings.

I had the same error.  My guess for me was that vxmon.exe was running at 10 to 50% CPU.  I rebooted the server.  Set the agent utility not to launch.  Set my selection list to not use the favorites.  Set my selection list to only backup the information stores.

Had this exact same problem couldn't back the storage groups at all even though all the tests worked OK.  Firstly, logged into Outlook Web Access with the Backup account details to check it could get access OK.  Then went to Start>All Programs>administrative tools>Domain Security Policy.  this brings up the default domain security settings snap in.  Go to Local Policies>User Rights Assignment and then add the backup operators, administrators, etc to the following entries:- Allow logon locally; backup files and directories; log on as a batch job, log on as a service; restore files and directories; take ownership of files or other objects.

My Error came back.  This only happens when running incr.  Got any ideas?

The following error was returned when opening the Exchange Database file:

'-1022 There is a disk IO error. '

Steve, you say this error is fixed with 7170, but Im running 7170 and am having the problem. Im trying to backup the Public Information Store to Tape, with GRT enabled. The idea is that I rarely have to restore individual items from Public Folders, but I'd like the abiltiy to do so. I don't mind the fact that the store has to be staged to disk first.

 

The article that comes up when clicking the link on the job log refers to disabled Mailbox accounts...is there anything I should be looking at with regards to mail enabled public folders?

 

Also, when this error occurs, the Information Store does not show up on the Restore tab for the backup job. You can select the entire job to restore and it appears that it will attempt this, but none of the granularity is there to even attempt to restore an individual message.

 

I'd appreciate some help on this. Thanks.

General comments to all in this thread.

Comment to “Network Admin”, Rehman Memon:

As per “Backup Exec 11d Best Practices Guide: Agent for Microsoft Exchange Server Backup Exec 11d Best Practices Guide: Agent for Microsoft Exchange Server” (http://seer.entsupport.symantec.com/docs/285753.htm) – backing up Exchange Information Store using GRT (“Enable the restore of individual mail messages and folders from Information Store backups”)

2. When using the Granular Restore Technology (GRT) feature to perform Exchange data backups setting the Device to submit the data to a Backup-to-Disk folder is preferred. This will allow an image on disc, which can be used to create restore selections dynamically, and could greatly reduce the time required to restore individual Exchange data items. Make certain the B2d location is on a Local NTFS volume and is not on a NAS, ISCSI or USB attached device

 

Comment to Sysadmin:

It looks like you are backing up “Legacy Mailboxes” (individual mailboxes), which is no longer necessary, as you can backup jobs of the Information Store with (“Enable the restore of individual mail messages and folders from Information Store backups”.  To potentially correct this, simply deselect the icon “Microsoft Exchange Mailboxes” (and Microsoft Public Folders) from the job properties, and only select and backup the Microsoft Information Store icon.

For Backup Exec for Windows Servers v11d rev 6235 - if you would like to have the “Legacy Mailboxes” icon removed from the backup selection list, deselect “Tools | Options | Microsoft Exchange | Legacy Mailboxes”

To find further information regarding GRT Exchange backup, please see “Backup Exec 11d Best Practices Guide: Agent for Microsoft Exchange Server Backup Exec 11d Best Practices Guide: Agent for Microsoft Exchange Server” (http://seer.entsupport.symantec.com/docs/285753.htm)

Comment to Navar Holmes:

Please make sure you have created the Full and the Incremental jobs using a Policy.  Furthermore, the job has to be backed up to a “Backup-to-Disk” folder  to be supported (“Make sure the B2d target location is a LOCAL NTFS volume (issues may be encountered if drive is attached in a manner other than IDE, SATA, SCSI, SAS or Fiber). USB attached devices are considered "removable hard disks" and are not able to provide an acceptable throughput for Exchange GRT B2d operations. NAS devices, mapped drives or DFS shares (or other linked volumes) are not local and can not correctly support the permissions required to read the Exchange data correctly. Please see the Admin Guide for 11d page 1230 for additional details.”).

 

Comments to Jerry Battaglia:

If you are backing up Public Folders with GRT enabled to tape, you will not be able to restore individual Public Folder. GRT for Public Folders is only available if backed up to disk.  (http://seer.entsupport.symantec.com/docs/287426.htm - “No restore selections for Backup Exec Granular Restore Technology (GRT) enabled Exchange Incremental backups”)

Please see the above technote for “Information Store does not show up on the Restore tab for the backup job”

 

Hopefully, the above answers many if not all questions - please let me know.

Christiane

Still having the error problem.  I am using a policy.  I have two (VIP and First) stores.  My daily full runs just fine for both stores.  I have the policy/template run a incr every 3 hours starting at 6am to 6:15pm.  But here is the kicker.  The  VIP incr runs but the First fails with the error.

 

When I was using the stripped down version of Backup Exec AKA NTBackup to backup my Exchange server.  I had no issues and I mean none.

To get good backups I had to go back to using NTBackup.  11D is just to buggy right now to use on Exchange.  It is more important to get good backups than being able to restore a single message.  Plus NTBackup is faster.
