fireberd: as you surmised and slartabartfast suggested, the problem you encountered was due to the Linux bootloader (iirc, Grub) used by Acronis lacking necessary hardware support for your very recent motherboard's SATA controllers.
The WinPE version you downloaded from MS is more current (it has to be, to allow installation of Windows on newer systems) and so had no problem installing the necessary SATA/AHCI support so that your drives became visible to your Acronis recovery application.
jbow: it is really incorrect to generalize cloud backup/storage as risky, because if implemented correctly by a cloud backup/storage provider your data is stored in several separate locations (replicated and spread across
the "cloud") for safety and fault tolerance, rather than in only a single vulnerable location (like in a single data center, which is probably where CW's servers were/are located). Lots of big companies are moving their data (and their servers also) to cloud services for that reason (there are other reasons as well, like accessibility, but data safety/fault tolerance is a biggie). But, it costs, and cloud services differ.
Amazon S3 is probably the most reasonably priced cloud solution for regular consumers, and is very robust, but it requires some technical expertise to set up and use. There are cloud storage companies which will do the heavy technical lifting for you (many simply use Amazon's or other cloud systems but have easy to use web interface front ends).
Expect many more cloud backup/storage services to appear, since the recently launched Windows Server 2012 enables cloud storage deployment and management. So prices may hopefully come down.
Meanwhile, besides Acronis, for backup/recovery there are some other low cost (and even free) applications I've used which might be of interest:
