Backup exec keeps failing

Hi there,
I have been having a consistent problem with backup exec when carrying out backups on my company's network.

Every night, I keep getting the failure message halfway through a backup job. Some of these messages are:

e00084ed - A hardware error occurred.
e00084af - The directory or file was not found, or could not be accessed.
e000fea9 - The Backup Exec data store encountered a problem during the operation.

I have changed the SCSI card on the server it is connected. I have also tried changing the SCSI Cable as well as well changing the SCSI ID on the backup drive from 6 to 5.

Furthermore I have reinstalled Backup Exec amongst other things. I am completely unsure what to do. I would call Dell who have supplied both pieces of hardware (Dell Powervault 114T and Poweredge 2650). But I would rather go through possible solutions onsite before calling them to diagnose and possibly replace hardware.

Can anyone help? Many Thanks in advance!

What are the directory or files that are failing? Do they exist?

If they don't exist, can you switch to text view in the selection list and see if they are listed there.

BUE is not to clever and often trys to backup directory's even after they have been removed. YOu can't see this in the graphical selection list but the text view may show you.

Failing that, can you list some of the full error messages please.

Well I am trying to back up Exchange and numerous other servers... Files and mailboxes are deleted all the time and I havent had a problem before... but now I am getting error messages such as...

1. Backup- \\<server>\Microsoft Exchange Mailboxes Storage device "CERTANCE 1" reported an error on a request to write data to media.
Error reported:
The request could not be performed because of an I/O device error.
V-79-57344-34029 - A hardware error occurred.

2. Job ended: Saturday, August 11, 2007 at 8:42:14 PM
Completed status: Failed
Final error: 0xe00084ed - A hardware error occurred.
Final error category: Backup Device Errors

For additional information regarding this error refer to link V-79-57344-34029

ALSO... when trying to back up my active directory and file server (both on the same backup job).. here is something i get..

Hope this is the info you need.

Many Thanks
Regarding the NtFrs_PreInstall directory not being found, see this article:  http://seer.entsupport.symantec.com/docs/276102.htm.  

Make sure you are up to date on service packs and updates/hotfixes.
Also, since it sounds like you're having hardware issues, download the latest driver pack for your server, tape library, tape drive, and SCSI devices.

Backup Exec support has often told me that sometimes the easiest fix is a second backup, appending to the same tape.

You may want to backup Exchange and AD as separate jobs to the same tape.

Also, for Exchange Mailboxes, do not have Backup Exec do them.  I implemented the method at this link, and never looked back: http://www.petri.co.il/brick_level_backup_of_mailboxes_by_using_exmerge.htm

Do you have any events with event id 7, 9 or 11in the System event logs at the time the backup failed with the "hardware error"? (for example around  8:42:14 PM on Saturday, August 11).
If you have event 7 messages, you may have a bad tape or bad tape drive. Event 9 or 11 messages could suggest problems with components on the SCSI bus.

Try cleaning your drive.
Update drivers & firmwares for the devices as snoopfrogg pointed out.
After that, if you can rule out that one or more bad tapes are the problem, I would go ahead and call Dell.

Honmapog,

Had a backup last night and after your messages regarding Events 9 and 11. The backup failed, looked in event viewer and these 2 messages came up.

Event 9 ---- The device, \Device\Scsi\adpu160m2, did not respond within the timeout period.

Event 11 ---- The driver detected a controller error on \Device\Scsi\adpu160m2.

These occurred one after the other. So would it be an issue on the server side or the external backup hardware?

Many Thanks

It could be a problem on either server or tape hardware side.
These event id's suggest an error on the SCSI bus. This could be anything of Adaptec SCSI controller, SCSI cable, drive or SCSI terminator.

Try checking for a loose cable or SCSI terminator.
Make sure the "Removable Storage" service in Windows is set to DISABLED.
It looks like you have a dual channel Adaptec SCSI card. You could try to move the SCSI cable to the other channel (other SCSI connector on the SCSI card).
And one last thing would be to check the Dell support site for updated drivers for the Adaptec SCSI card (although this is not likely to be the problem if this worked fine for months).

If these suggestions don't work, I think only a hardware replacement will solve the problem.
