If you don't take the whole disk image to preserve the boot,
partition, and label info, you might as well use a file
based copy technique.  'cp -a' will work, or if you are
doing it repeatedly to stay up to date you can do:
 rysnc --delete --one-file-system -avH source_dir dest_dir
where the source/dest are the mount points of the partitions.
