VM backup: Failed to open virtual disk file

Our VM Backup Job fails, if a manually created snapshot exist on the VM (created through the VM Center Console).
Acronis reported:
Failed to open virtual disk file
You do not have access rights to this file.
>> See the attached Error Message.
We use ESXi 5.1 and vCenter 5.1. The Acronis User for the vCenter integration has admin rights on the vCenter/ESXi.
This is a problem, since we updated to ESXi 5.1 / vCenter 5.1.

From a Acronis VMProtect Manager, we received this Input:
1) Rename the C:\Program Files (x86)\Common Files\Acronis\VirtualWare\VixDiskLib\plugins\ folder on the machine where you have installed Windows Agent for vSphere into some other name (plugins_old for example) and retry the backup operation. This action will disable LAN-free mode (direct SAN access) and will enable more extensive logging. If this method doesn't work then I'd recommended to contact Acronis support regarding this issue since it does look like a product problem (logical error).

When I follow the instructions from Vasily (Acronis vmProtect Program Manager) (http://forum.acronis.com/forum/32177#comment-125561), the backup works also on VMs with manually created snaphsots. So the problem is related with the diskLibPlugin.dll.

Is this a known problem? Any others with this issue?

Turn off the virtual machines that use persistent disks before you back them up;

That worked for me.
