A snapshot is a stored map of the HDD sectors reflecting the HDD’s state when stored. The actual size of a snapshot is less than 0.1% of the HDD capacity. Protected sectors are often linked to several snapshots in parallel and remain protected even if the corresponding data is “deleted”. Sectors linked to snapshot/s are freed only after the “parent” snapshots are deleted.
