Backup Exec 11 D AOFO error

[mpaniak]

Backing up some data from a server to an attached SCSI tape drive.  Error is as follows:

V-79-57344-34110 - AOFO: Initialization failure on: "D:". Advanced Open File Option used: Symantec Volume Snapshot Provider (VSP).
Snapshot provider error (0xE000851C): Cache files required for the Symantec Volume Snapshot Provider (VSP) snapshot could not be created. Check that there is at least 50 MB of free disk space, and review the settings for the snapshot that are reported in the job log.

Check the Windows Event Viewer for details.

AOFO: Symantec Volume Snapshot Provider (VSP) snapshot cache file settings for volume "D:" : Initial: 0 MB. Maximum: 60341 MB. File: "\\?\Volume{cb120ab8-b6a7-11db-93ad-806e6f6e6963}\Backup Exec AOFO Store\_BEVspCacheFile_0.VSP".
AOFO: Symantec Volume Snapshot Provider (VSP) snapshot settings used: Quiet Time: 5 seconds. Time Out: 2000 seconds.


The files are not in use as they are backup files residing on the server from the weekend.  The backup server itself has tons of disk space.

Any idea what is causing this?

Hello,

I believe the error message V-79-57344-34110 - AOFO: Initialization failure on: "D:". is on Windows Server 2003. If so, please follow the steps below:
1  : Open the job properties.
2  : Navigate to the "Advance Open File" Opion
3  : Check the Radio Button "Microsoft Volume shadow copy service"
4  : Snapshot provider dropdown..select the second option "System:Use Microsoft Shadow Copy Provider"

We need to make sure that "Shadow Copies" are enabled on the D-Drive of that particular Server
1  : Go to the properties of the D-Drive
2  : Click on the "Shadow Coipes" TAB
3  : We must see all the Partitions under "Select a Volume"

Please let me know the results...

Hi

I am agree with you that he need to change the snapshot provider to Microcoft Shadow Copy Providerbut no need to enable shadow copy on D volume.

The steps for setup AOFO is as follows. These steps are as per the guidelines

1. Install remote agent with AOFO on remote server and reboot the server. If it is local backup serever then no need to install remote agent.
2. On remote server make sure that you have sufficient free space available on any drive
3. The data which you need to backup, should not be resides on that drive.
4. Minimum free space should be 20-25% of data which you want to backup.
5. Create a folder on that valume (name can be AOFO)
6. Set this folder to store the snaps

To manually set this folder as a snapshot folder please find the configuration steps below

1. Open backup exec console on backup server
2. Click Tools-->Wizards-->Advanced Open File Option Wizard
3. Click Next, Select the server, Provide authentication & click Next
4. Uncheck Use Default, "drive letter"\AOFO, click insert & then click next
5. "Number of seconds during which  there can be no disk activity.............." set value to 3 sec & click next
6. Click OK  & Click finish

Perform the backup job again.

Just make sure you dont reduce the quiet time more than 2 secs

Make sure the Antivirus is not configured to scan cache folder for AOFO at the same time job runs

hi,

Exclude *.vsp from antivirys scanning.........
Also if backups run in non working hours simply dont use AOFO...
Please install latest Hotfix of VSS from microsoft.

Definately solves problem

Forgot to tell you...

Also exclude *.vsp & vsp.sys from AV scanning on the remote server

vsp.sys file will be available in windows\system32 folder

Please check and confirm
