It keeps a full copy of your data offsite, plus deltas to get you back to older versions. I'm currently backing up a 70GB dataset each night. On days with no activity it is taking less than an hour and I have a convoluted setup. (I first backup locally to encfs encrypted fs, then rsync the whole backup repository to an offsite location.) When there is data to send, I'm getting about 1GB/hr. The rsync algorithm ensures that only the deltas get sent. (rdiff-backup uses the rsync algorithm too.)
