According to this forum

For Win 8 only: The Win 7 back up program included with win 8 does not support backing up a image file to any kind of NAS device (UNIX, Linux) . Internally the program gives an error that the NAS device has an incompatible sector mapping type. You can backup to a hard drive that is attached to a different windows machine and then back up that file to your NAS. Convoluted, but it works.

So, backing up a system image to a Samba share is out of the question. To work around this, disable the creation of a system image in your backup.

I haven’t tried backing up to an NTFS-formatted iSCSI LUN, which might work. If anyone has tried that, I’d be interested to know the results.
