Backup Exec cannot attach to resource

I'm running a Windows 2003 Server with SP2 and MS Exchange 2003 (SP2). Backup Exec is installed with all the latest updates for 11d (Remote Agent).

I can successfully backup this server using GRT but I cannot perform a restore to any of the mailboxes. The error I receive is, Final error: 0xe000848c - Unable to attach to a resource,  V-79-57344-33932.

Please help!
Watch Question

Is your original backup going to disk?
If it is, and the restore doesn't work, make sure that the following applies for the logon account you use in the restore group:
* Logon account has a mailbox associated. The mailbox has been sent at least one email
* The logon account's mailbox  is not hidden from the global address list
* The logon account has been delegated Full Exchange Administrator permissions from organisation level in Exchange System Manager.
* The logon account's mailbox name is unique in the organization (http://seer.entsupport.symantec.com/docs/256537.htm)


Yes we are writing to disk and then to tape. The restore is coming from the tape though because we only keep the disk backup for 1 week and use the tapes for longer periods.

All the points you made have been adhered to but I'm still getting the problem.

Is the logon account a domain admin? And is the logon account a local administrator on the Exchange server (make sure it is a local administrator on its own, and not explicitly through group membership).

Also try the following: in Tools/Options/Microsoft Exchange enable the option for "Legacy mailbox backup". This will add a new entry with name "Microsoft Exchange Mailboxes" to the selection list. Try selecting that selection with the same Logon Account you use for the restore. Does that work or does it throw an "Access Denied" or "unable to attach" error.


The account is an administrator on the local server.

Already had the legacy option enabled before I posted this.

When I run a test with the account I use, it passes. I've tried accessing mailboxes through Outlook with this account also and it can open them fine. You would think that you could do a restore with the same account but for some reason it fails...

I  suggest create a completely new account with all the requirements and try again.

Try enabling debug logging on the Remote Agent service. I can't guarantee I'll see something, but I'll try.


Just a quick question, do I need to take the store offline whilst trying to do a recovery?



I am now getting this error after tweaking the resource credentials to use my purposely created veritas account,

No - you don't need to take the store offline.

It still looks like you're logon accounts have sufficient permissions.

Ask the Experts


When I researched the article it claimed the error was due to the job trying to write the data to a compressed disk. That is not the case for me so I'm still lost...

I meant to say "insufficient permissions" in my previous post.

Try enabling debug logging on the Remote Agent service. I can't guarantee I'll see something, but I'll try.


Could you explain how I go about this please?


Never mind. Cracked it by completely deleting the temp staging area and tweaking the permissions.


Just need to delete the staging area because this might have been written back to disk in a corrupt manner.
