"AOFO: Initialization failure" and "Snapshot provider error (0xE0008524)" is reported in the failed backup job log

Problem

AOFO: Initialization failure on: "C:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS). Snapshot provider error (0xE0008524): Unable to initialize the snapshot because the Advanced Open File Option (AOFO) is not installed on the target computer.

Error Message

Scenario 1:
While doing an AOFO backup, the following error is encountered in the failed Job Log.

AOFO: Initialization failure on: "C:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0xE0008524): Unable to initialize the snapshot because 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.

The error above occurs, even if AOFO is installed properly on the machine, and the Remote Agent debug log shows the following:

Cause

This above error can occur if the Backup Exec (tm) service account has not been granted the correct privileges (including privileges for group policies) or can be due to VSP driver file corruption on affected machine.

 

Solution

The account should have Full Administrator rights on the server being backed up.  Also, the following rights may be assigned to the account through the group policy:
 
1. Act as Part of the Operating System
2. Backup Files and Directories
3. Create a Token Object
4. Logon as a service
5. Manage Auditing and Security Log
6. Restore Files and Directories
7. Take ownership of files and other objects.
