Incremental sends capture changed blocks. Snapshots capture all of the FS state as of the time the snapshot is taken, though it does so in constant time. Subsequent changes are kept as changed blocks, as deltas to the snapshot in the filesystem and clones. > That is, assuming that the snapshot (destination) stays inside the same > pool space.
