Windows 7: Backing up Dynamic disks

Hello all,

I am running Win7Pro64. I have the following config

- 2 HDs mirrored for the OS
- 2 HDs striped for DATA

All HD are configured to be dynamic.

I am looking for a software that will create an image for my drives.
Windows built in Backup and Restore backs up the drives but then when I try to restore .... it doesn't find the image that is stored on a NAS.
I can log on to the NAS but Windows fails to find the image

Thanks
