I've tried running the rsync command from the log file.  It doesn't 
produce errors, but even turning up verbose doesn't return anything useful.

[backuppc@sinope ~]$ /usr/bin/sudo /usr/bin/rsync -vvv --server --sender 
--numeric-ids --perms --owner --group -D --links --hard-links --times 
--block-size=2048 --recursive --one-file-system --ignore-times . /
FILE_STRUCT_LEN=16, EXTRA_LEN=4


Is all I get regardless of how long I let it run(including the 
unprintable character).  If I check filesystem usage periodically, it 
doesn't change, so it doesn't seem to be backing up anything.
