Doing Deltas is fine, up to a point.
One should do a full backup once a week, and then do incremental backups for the other 6 days. Rinse and repeat. If you do nothing but deltas after that first backup, restoring becomes a nightmare. Could you imagine trying to do a full system restore with one full backup, and 700 days of deltas?
The source and destination folders will be the same after running rsync. An rsync backup is the equivalent of a full backup, except only the deltas (or differences) are transferred. By transferring only the deltas, the backup will be a lot quicker than copying everything from the source to the destination.
