RESOLUTION and DOWNLOAD.

After some, I found the problem is connected with Microsoft Shadow copy Service. I decided to delete all shadow copy in my host and I am able to backup all my server again.

I used those commands line in a Powershell window:

Order	Command	Description
1	DiskShadow	Connect to DiskShadow Tool
2	Delete Shadows All	Delete All Shadows Copy
3	List shadows All	Check the list is empty
4	Exit	Disconnect to DiskShadow Tool

Once, the command has been executed and you should is able to relaunch your backup.

However, this ERROR CAN still comeback!

You has to delete again manually the Shadows copy or can execute my script (deleteshadows). The instruction is include in the RAR file.
