This is indeed a reason why backing up to mapped drives isn't supported
with Windows Vista.

According to Microsoft, to use a NAS device as a backup target, you
need to create the share with "Full Control" privileges for the user whose
credentials they want to connect with.


If this doesn't work, contact your NAS manufacturer to ask them for
upgraded firmware based on 3.x version of Samba.

I've got an Iomega NAS on my network and would very much like for this to be
my destination for the Vista Complete Backup. However, the only valid
destinations are another physical hard drive or a CD / DVD. Ironically, the
Backup Files option does in fact allow me to enter a network drive path and
can see my NAS just fine. Why does the Complete Backup not allow for this?
Please advise! Thanks in advance.
