The -a option might be a good choice, and i like the --one-file-system
as well, for backup purpouses. Its very convenient to be able to restore
partitions separatly, without having to remember whats mounted where and
'what parts of this and that did I archive'.
rsync is nice too. And faster... Just remember not to rsync to a non
UNIX FS, as that would cause some troubles with permissions and other
things.

Good luck. :)
