Missing installation CD, MY BOOK ,1TB

I purchased MY BOOK  2.0 without the CD, manual (or WDSmartware as far as I could discern). After I downloaded the WDSmartware, I discovered 2 programs for purchase—Autobackup & Autosync. Apparently these are included free in other models of WD external drives.

Has anyone had experience with Autobackup? It seems to be a more comprehensive and better than WDSmartware? At least I could install it.

I would greatly appreciate early responses.
