    Suppose you create a full backup on Friday.

    A differential backup on Monday will save only the changes made since Friday.

    A differential backup on Tuesday will also save all the changes made since Friday.
    An incremental backup on Tuesday will only save all the changes made since Monday.

    So a differential backup saves all changes since the last full backup, but an incremental backup will save all changes made since the last backup of any type.

    There's a good explanation, with examples, here:

    Rsync always works differential. It will only sync files that have changed since the last time you ran rsync.
