Hi all,

I am running Symantec Veritas\Backup Exec 10d. On one of my servers, the daily job completes at times and then completes with exceptions. The daily operation for the server is the same everyday (Database server running SQL).

I am getting this error:
AOFO: Initialization failure on: "\\Servername\C:". Advanced Open File Option used: Symantec Volume Snapshot Provider (VSP).
Snapshot provider error (0xE0008500): The Advanced Open File Option (AOFO) is not installed on the target computer. You must install this option, restart the computer, and then run the job again.

Backup- Servername
AOFO: Initialization failure on: "\\ServenameC:". Advanced Open File Option used: Symantec Volume Snapshot Provider (VSP).
Snapshot provider error (0xE0008500): The Advanced Open File Option (AOFO) is not installed on the target computer. You must install this option, restart the computer, and then run the job again.
Check the Windows Event Viewer for details.

Why does it run with no exceptions one day and with exceptions the other?

On the days it does work, if you look through the job logs, what snapshot method did it say it used behind the "Advanced Open File Option used" string. Did it use Volume Shadow Copy Provider (VSS) or Symantec Volume Snapshot Provider (VSP)?

If it used VSS when it works, you may try to change your jobs and fix the snapshot technology to VSS, instead of leaving it on "Automatically select provider"

Sorry, I mislead. The backup jobs are different. The only ones that complete without exceptions are regular servers. The ones with exceptions are all Database servers using VSP. Should I change it to VSS on the Database servers?

Yes, change it to VSS.
However, if you're backing up SQL databases or Exchange, Symantec don't really recommend using AOFO on such jobs.
So for the database servers I would split up the jobs in 2: one job without AOFO for databases. Another job with AOFO fixed to VSS for normal file system volumes.

Of course those database servers need to be Windows 2003 - otherwise VSS is not available.

If these servers are Windows 2000, you'll need to use VSP. In that case, make sure you installed the AOFO component of the remote agent on those servers.

I changed the backup from VSP to using VSS. I got more errors this time.

Backup- \\SERVER1\Z: Backup
Directory SERVER2\Backups\Post Server Error\ was not found, or could not be accessed.
None of the files or subdirectories contained within will be backed up.
Directory \\SERVER1\Z:\SERVER2\Backups\Post Server Error was not found, or could not be accessed.
None of the files or subdirectories contained within will be backed up

Backup- \\SERVER3\Z: Backup
WARNING: "\\SERVER3\Z:\SERVER2\Backups\DV3.sqb" is a corrupt file.
This file cannot verify.
The item \\SERVER3\Z:\SERVER2\Backups\DV.sqb in use - skipped.

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

In this last attempt- what did the "Advanced Open File Option used" line in the log show?

The Z: drive on which you saw the errors did not seem to be part of the above list.

Sorry, I neglected to copy

AOFO: Started for resource: "\\SERVER2\Z:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
The snapshot provider used by VSS for volume Z: - Microsoft Software Shadow Copy provider 1.0 (Version 1.0.0.7).
Network control connection is established between 192.X.X.X <--> 192.X.X.X:10000

I dont know why I get "Directory SERVER2\Backups\Post Server Error\ was not found, or could not be accessed" if I'm using VSS instead of VSP.

I switched back to VSP and got a few successes with exceptions. I dont know if this has something to do with it but now I got:
AOFO: Not enough disk space on the device running the Advanced Open File Option (AOFO) to create or increment the cache file.
To increase the initial size and maximum size of the cache file, use the AOFO Wizard on the Tools | Wizards menu.
Optimum settings for your computer will vary.
Snapshot error during backup. Set has been canceled.

If its a totally different issue we can just focus on the original problem and ill open up another thread for that one if need be.

Thank for your help!

Basically I have to re-arrange thejobs around. I used VSP for some and VSS for others and it is working.

Thanks honmapog
