There's your problem.  The mode bits are a property of the inode, not of
the directory entry, so next time rsync goes to look at a file whose
mode you've changed, it looks different so gets uploaded again:

$ touch foo
$ ln foo bar
$ ls -il foo bar
819403 -rw-r--r--  2 cantrelld cantrelld 0 Jul  6 12:38 bar
819403 -rw-r--r--  2 cantrelld cantrelld 0 Jul  6 12:38 foo

# now try to change mode of just one of those ...

$ chmod 755 bar
$ ls -il foo bar
819403 -rwxr-xr-x  2 cantrelld cantrelld 0 Jul  6 12:38 bar
819403 -rwxr-xr-x  2 cantrelld cantrelld 0 Jul  6 12:38 foo

And why on earth would you want to make everything in your backups
executable - and even worse, executable (and readable) by everyone?
