Hi,

Since we installed the new version of Data Protection Manager 2012 R2, we get issue messages while backing up Windows Server 2008 R2 or 2012 R2 virtual machines. 

At every backups we will find the followings in Event Viewer:

Log Name:      System
Source:        partmgr
Date:          18.2.2014 21:40:34
Event ID:      58
Task Category: None
Level:         Warning
Keywords:      Classic
User:          N/A
Computer:      server01.domain.local
Description:
The disk signature of disk 2 is equal to the disk signature of disk 0.

This last line is repeated for each disk.

Sometime this line is preceded by the following:

Log Name:      System
Source:        VDS Basic Provider
Date:          20.1.2014 20:08:58
Event ID:      1
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      server01.domain.local
Description:
Unexpected failure. Error code: D@01010004

The registry is growing up with remaining entries under:

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2

May someone help me? Thank you

Regards,

Samuel
