I like to use rsync to transfer data from our off-site systems.

It's reliable and efficient, and can be tuned to copy/backup only data that has changed (note data: not necessarily re-copy the whole file that has changed, but the portions which have changed).

It's an excellent tool, and can be combined with SSH to utilize encryption to protect your data en route.
