I got the same error. Environment: Win 8 Pro 32 Bit, i do upgrade from Win7 Ultimate. Backup on Zyxel NSA320.
Same for me saving to a NAS drive. I used "Let me choose settings and deselected anything that I had transferred to the Nas. and also no system image. It completed but still tells me it couldn't back up files that are on the Nas, but at least I have a backup.
i have the same problem.
Win 8 Pro x64 to HP Microserver n40l with NAS4free.
I have tryed it several times. The samba share ist error free.
It is a shame for Microsoft.
It works without including system image...
of Win 8 Backup, since you have to reinstall everything in case of harddrive crash.
Not only reinstall but perform all updates and redo all of the configurations. I don't know about you, but redoing preferences for a program that I normally just have running in the background frequently takes 1/2 an hour or more as I research the settings. Reinstalling all windows updates alone forget Adobe, Java, Sony, Nero etc. can take hours.
