I installed Veritas 9.0 on a new exchange server in a Windows 2003 domain. I am attempting to backup out the exchange files. I setup a job to backup all exchange files. When the job is verifying it returns with:

Final error code: a000848c HEX
Final error description: Unable to attach to one of the drives.

Is the tape ejected before the verify runs?

Negative the tape is not ejected before the verify runs.

I just ran a backup right now. The backup seemed to backup the data fine. The verification starts and seems to run almost the entire way through. When it completes this is the alert that is on the screen:

Exchange All -- The job failed with the following error: Unable to attach to one of the drives.

This suggests that BE is unable to attach to one of the HDDs (perhaps on the Exchange server). If you examine the logs, on which drive does it fail?

I would never verify backups you have made of exchange. First the verify doesn't really do much except waste time, but almost allways you will have changes to all mailbox data while doing the backup, so you will allways have differances from what you backed up and what you verify later. The mailbox will have received new mails, etc. So doing a verify of mailboxes will just give you errors. What I suggest is to restore random mailboxes after a backup to check if the backup is OK.

Ok I tried running the backup without verifying and it still returned the same error message. Here is the full message from the log:

Job Completion Status
Job ended: Tuesday, March 01, 2005 at 11:18:59 AM
Completed status: Failed
Final error code: a000848c HEX
Final error description: Unable to attach to one of the drives.

Final error category: Resource Errors


any ideas?

Apply all patches and SP's from the Verita's site. Also make sure your Server has been made up-to date.

I have seen a similar problem when trying to restore both the Private store and Public Folders store (the Public folders are restored along with the mail store, so the additional selection is redundant). If you de-select Public Folders does the error go away?

Media 'DLT000017' is overwrite protected.

Do you know how to remove this. I am trying to backup a single test file to see if that works and I get the error message above and the tape ejects itself.

Check if the hardware write protect tab (a slider on the case of the tape cartridge) has been set.

Overwrite protection (not the same as H/W write protect) is set as an option in BE. I'll post the method to alter this shortly...

Meyersd I beive that is what I am looking for.

I ran a backup of a test file without any problems. However when I try and then do a backup of something else it says that it is not overwrite protected. Instructions on how to fix this would be greatly apprecieated.

Tools -> Wizards -> Media Set Wizard

Select the media set that you want to change and set the Overwrite protection period that suits you best.

Ok the problem was that there was an account called administrator1 with its own mailbox setup. Veritas would get up to this mailbox each time and then choke. As soon as I removed this mailbox the backup ran just fine.

The solution is clear. It was a result of having several accounts with similar names. IE you cannot have and admin account and and administrator account as the logon account for Veritas. As soon as I deleted the administrator1 account everything started working fine. It took alot of trial and error to isolate the problem. I can find no reference to this same problem on the net and would suggest leaving it up in hopes that it will help someone in the future.
