rsync - Jun 2003 - Local copy (root to mounted subdir) wanted - protocol error in io.c

Hello everybody,

maybe someone has also had this issue:

I try to copy the root partition "/" to a subdir
"/Volumes/System". This is
not a cyclic recursion, because "/Volumes/System" is a mounted hard
disk
partition. So I gave rsync the parameters "-x" for one-file-system,
and
'--exclude "/Volumes/" ' also:

# rsync -ax --showtogo --stats --exclude "/Volumes/" / /Volumes/System

But I get a protocol error (broken pipe) in io.c. When copying all the 
subdirectories manually, everything works, so I think he tries toa void a 
cyclic copy.

(I'm using rsync 2.5.5, or rather rsyncx 1.7d, a special version for Mac OS 
X.  I've booted the computer from a FireWire harddisk, and I try to clone 
that boot partition to the local harddrive already having many of the 
files).

If someone has made a local copy like this - with or without success - I'd 
be thankful for an answer.

Have a nice day,
Viktor.

A broken pipe means that the process on the other end of the
pipe died.  "broken pipe" is not the error message that
means anything.  It is the error message (if any) from the
process that died that matters.

You need to contact the supplier of this modified rsync.  We
cannot support binaries made from modified sources.
Alternatively download and build rsync 2.5.6, or better the
version in CVS.

This sort of thing is done all the time for making backups
using vanilla rsync on Unix, Linux and even cygwin.
