WD My Book 4T and Acronis True Image WD Edition

Just purchased a WD My Book 4T and want to use Acronis True Image WD Edition.   One of the few backup technologies that documents the recovery of files or whole/part of images/devices.  Acronis TI WD edition does not concider the USB connected WD My Book 4T as a valid WD device.  This is going to take an additional $30-50 purchase for a backup/restore solution.  I will try the trial version of Acronis True Image 2013 before purchasing.

The WD version is based on TI 2009 so it’s outdated and meant for cloning or making an image not incremental backups. I think they may be in the process of updating it but don’t know when.
