Abstract: Components of a distributed data object are synchronized using streamlined tracking metadata. A target component of the distributed data object is detected as it becomes available and stale. A source component that is up-to-date and that mirrors the address space of the detected target component is identified. A set of mapped address ranges and a set of unmapped address ranges of the identified source component are obtained. A mapped address range of the target component that corresponds with an unmapped address range of the source component is identified. The identified mapped address range of the target component is then synchronized with the corresponding unmapped address range of the source component. Thus, unmapped address ranges are synchronized without using tracking metadata of the source component.
