I agree on the rsync. It can be a little confusing to setup (I haven't played with it in a while).
But it's a great tool for syncing backups

Here's the problem with dd: it will happily copy over bad sectors. And then, of course, your backup's useless. Rsync is a better alternative, and can be used to "update" a backup already in place. But rsync is a file-by-file, not an image backup. Avoid tar, as bad spots (for whatever
reason) in the middle of a tar archive will invalidate the rest of the archive.
