Backup Exec 11d services die on Exchange 2003 backup

Hi,

I'm getting a weird Backup Exec issue. I've got 11d for SBS2003. It's been installed and running just fine for almost 5 years now. Patches up to date.

I was backing up to DAT72, but these tapes were recently filling up. I've started using Removable Backup-to-Disk folders on USB disks. I encountered an issue whereby backups would run fine, but as soon as I started backing up Exchange, the Backup Exec services would "unexpectedly terminate". Exchange would backup fine to tape, but not to Removable B2D folders.

The weird part is, a few days later, backups to DAT72 have ALSO started failing when backing up Exchange. The Report log says:

 

 

 Backup of "\\SERVER\Microsoft Information Store\First Storage Group "

Backup set #1 on storage media #1

Backup set description: "Exchange Backup"

Backup Method: Full - Database & Logs (flush committed logs)

Microsoft Exchange Server Agent: Started

The option to enable the restore of individual items from the database backup was selected for this backup.

Backup started on 24/11/2011 at 02:39:54.

The consistency check of the snapshot for the Microsoft Exchange transaction log Logs was successful.

The consistency check of the snapshot for the Microsoft Exchange database Mailbox Store (SERVER) was successful.

V-79-57344-65072 - The Exchange Store service is not responding. Backup set canceled.

V-79-57344-34108 - An unexpected error occurred when cleaning up snapshot volumes. Confirm that all snapped volumes are correctly resynchronized with the original volumes.

======================================================================

Job ended: 24 November 2011 at 02:43:29

Job completion status: Failed

======================================================================
 
I've tried the following:
  • Run eseutil on the Exchange databases - no issues found
  • Used NTBackup to backup Exchange - backup was successful
  • Turned off AOFO - Backup still unsuccessful
  • Backed up Public database only - backup successful
  • Backed up Mailboxes store only - backup unsuccessful
  • Rebooted the server - backup still unsuccessful

There's nothing of note in the Windows event logs, other than the service terminating. Usding Job monitor, the job runs for less than a minute, with a byte count of less than 1MB before the service dies. About a minute or two later, I get a "Job failed"

Can anyone please give me any pointers? I've searched forums and elsewhere with no success.

Many thanks in advance,

Alex.

    You should not be using removable B2D folders for your USB disks.  You should use normal B2D folders.  Removable B2D folders are meant for things like Jaz drives and RDX drives.

    Hi,

    Thanks for your post. Forgot to mention the agent is local. Don't think TCP offload would make a difference?

    Thanks again,

    Will try normal folders, thanks.

    I'll post any progress. 

    Any other suggestions guys & girls? Thanks again!

    Thanks, will make the switch, I'd not appreciated that.

    I don't think that's the cause though, as the agent dies when backing up to DAT72 too.

    Any other ideas anyone?

    Many thanks!

    Can you disable GRT option in the backup job and check if the remote agent still crashes during backup?

    Does this happen only for Exchange backups or for normal file/folders backup as well?

    Check application log if it shows any error when the service crashes.

    Thanks. Not sure there is a GRT option in 11d?

    This only happens for backups of the Exchange Mailbox Store. Exchange Public store is fine. Files and folders are fine.

    I've just tried unticking "Enable Restore of Individual mail messages..." (is that the same as GRT?) and the backup runs fine then. Would I be right to assume one of the individual messages is making the Agent crash?

    If so, how do I resolve this?

    Thanks fo your help!

    Forgot to add, Application log says:

    ESE:

     Information Store (5680) First Storage Group: Ending the backup of the file D:\exchange\mdbdata\priv1.edb. Not all data in the file has been read (read 851968 bytes out of 2826317824 bytes).

    ESE:

     Information Store (5680) First Storage Group: The backup has been stopped because it was halted by the client or the connection with the client failed.

    Then Backup Exec:

     

     Backup Exec Alert: Job Failed

(Server: "SERVER") (Job: "Exchange Backup(Private)") Exchange Backup(Private) -- The job failed with the following error: A communications failure has occurred.
     
    Thanks!

    Is GRT the same as "Enable Restore of Individual mail messages..."? I can see no reference to GRT in version 11D or its help file.
     
    I turned on "Enable Restore of Individual mail messages...", disabled AV and turned on AOFO. Agent crashed again when backing up the Mail store.
     
    The only success I've had is turning off "Enable Restore of Individual mail messages...". Job runs OK then.
     
    Any more suggestions? Thanks for your help all.
