When a vfat file system is mounted under linux, attempts to change the
owner, group, or permissions on files return errors, because vfat doesn't
have these things. 

I tried to run a test case using rdiff-backup 0.13.3 to a vfat filesystem,
and it failed trying to change the file permission modes. 

I do not know if mounting the filesystem as umsdos would help; 
might do bad things to the windows install.


Here's the error from the original report:

Anyone know what mode "wb" is?

Here's the error from an attempt I made using 0.13.3:
