Our Samba solution is implemented on Linux, with no quota rules
applied whatsoever. As I described in the OP, the problem I am having
does only occur when trying to save (overwrite) a file using the
standard save command ('C-x C-s'). If I use the "Save as" command ('C-
x C-w') instead, and specify the file name which I currently have open
and want to save, everything works as expected.

My backup files reside under my home directory, specified with the
'backup-directory-alist' variable.

I started emacs with the -q and -Q arguments and the problem persists.

Now, here is where it gets interesting - TRAMP works flawlessly. I set
it up this Friday and did some testing for a few hours and it haven't
had a hiccup yet.

If I open a file using the mounted Samba share, edit it for a bit and
try to save it (using 'C-x C-s'), Emacs gives me the error that it
can't find the file or directory. When opening it with TRAMP (using
the '/smb:/') keyword, I can save it without any problems at all!

I just tried editing a few files over the samba share with vim and it
works without any problems.
