I have not heard of this type of error before so I would tentatively 
suggest that it is not the fault of rdiff-backup but some other problem 
(filesystem corruption maybe?).

If this file is really missing and it is the *only* thing wrong with the 
repository, you might be able to fix it just by recreating it (as it was 
a nul file anyway) on the destination (this is for Windows command 
prompt, with Linux or Cygwin you can use touch):
<nul (set/p z=)

Another possible clause of your difficulty, more intractable, is that 
the path+name length for this 'missing' file is 272 characters - you may 
be coming up against the 260 character limit for Windows paths - see 
http://stackoverflow.com/questions/1880321/why-does-the-260-character-path-length-limit-exist-in-windows. 
I don't of a way around this one except to say 'rdiff-backup *from* 
Windows yes, but always rdiff-backup *to* Linux', which is probably not 
much help in your situation. You could try physically mounting your R: 
drive on a Linux system, copy the whole repo onto a Linux-based 
filesystem (e.g. ext4), and then try doing a remote backup from the 
Windows machine to the new repo on the Linux machine.
