Exchange Backups Failing

Been fighting with this problem for a very long time now and I am about fed up. What the deal is that we have and Exchange 2003 server and it is being backed up by a Symantec Backup Exec 12.5 server. We get the error: Final error: 0xe00084af - The directory or file was not found, or could not be accessed. Final error category: Job Errors

Backup- \\Exchange_server\Microsoft Information Store\First Storage Group Database  was not found, or could not be accessed.
Database  was not found, or could not be accessed.
Database  was not found, or could not be accessed.

We get this error and it appears that the only way to fix this is to rebuild the job. We delete the job, the policy, even the media set and the job will run the Full, it will even run the following incremental giving us false hope. The next day it fails again. We have the correct agents installed on the Exchange server and we also have an account that has owner rights of every mailbox and every public folder and we have also copied the Mapi32.dll from the Exchange server over to the Backup Exec server because we had seen that working for some people.

When we call into Symantec for help they like to have us chase our tails for days on end.

From the research on this problem that I have been seeing I believe this is actually a very common problem.

Hello,

Has anything change recently on the Exchange server or the Backup server to cause this issue?

Are you using the Backup Exec Exchange Agent or backing up the information store .edb file?

We are migrating the Exchange over to a new set of servers but this problem has been occurring long before the servers were even installed. We have stopped backing up our old servers just to less complicate things. The permissions are all still the same.

And yes, we are using the Exchange Agent for the backups. I would not think that we would get any backups completed if we were not using the correct agent.

Oh please note that we are doing GRT backups.

You can use the Exchange agent and you can manually backup the Exchange information stores.  Try to manually backup the Exchange server\Exchsrvr\MDBDATA(contains the .edb, .stm, .log files), what are the results- Backup was successful?

Im sure that would work fine if you want to backup the entire database. We want to be able to back up incremental files throughout the week so we dont use as much tape. So Im sure this method works, but so does our full backup through Backup Exec. Its the incremental backups that are tricky&

We ended up finding a solution to this problem. The Backup Server seemed to have problems keeping up with the Incrementals throughout the week so we changed the backup strategy to One Full backup every 4 days and incrementals in between. This seemed to have worked and it no longer fails.
