rsync and smbfs

[Jiann-Ming Su]

I'm trying to configure rsync snapshots as described at
http://www.mikerubel.org/computers/rsync_snapshots/.  I'm 
essentially using the following commands:

mv backup.3 backup.tmp
mv backup.2 backup.3
mv backup.1 backup.2
mv backup.0 backup.1
mv backup.tmp backup.0
cp -al backup.1 backup.0
rsync -a --delete source_directory/ backup.0/


I'm trying to backup two directories in a Windows 2000 share onto a RH9 linux 
computer.  The problem I appear to be having is rsync copying file that 
already exist and haven't changed since the previous rsync backup process.  
Why would rsync believe the file has changed?  Thanks for any tips and 
insight.
