I've been testing on Cygwin and I find it much improved over the last
time I tried it and gave up, several years ago.  Package management is a
pain, but at least it works.  Seems to be very compatible with Linux and
Windows both.

That said, I'm having trouble duplicating this problem, so I need to ask
you what kind of files are being backed up.  I've run through several
gigs of backup/restore using Cygwin, using both Windows files and Cygwin
files and have not been able to reproduce this.  The traceback is
literally saying that an object that is an instance of 'file' is not of
type 'FileType'.  I cannot see how that is possible.
