Backup Exec 2010 R3: Backup of a Japanese Windows 2008 VM to a deduplication folder fails with an error - Failed to mount one or more virtual disk images

Problem

During the backup of a Windows Virtual Machine in which the names of the .vmdk files contain an extended character set, the backup fails with the following error:

 

Error Message

Failed to mount one or more virtual disk images:

Error mounting disk(s): UNKNOWN_ERROR (0x00000002).

Cause

This problem is caused by the underlying deduplication software when trying to mount a .vmdk file.  This only occurs when using GRT to back up the Virtual Machine.

Solution

Workarounds:

 
Rename the .vmdk file so it does not contain extended characters.
Do not use GRT when backing up this Virtual Machine.
 

Solution:
This issue is now resolved in Backup Exec 2010 R3 Hotfix 159965
