摘要： In some examples, a system maintains, for a base storage structure and a collection of snapshots associated with the base storage structure, statistics relating to usage of storage space based on data of the base storage structure and the collection of snapshots. The system checks metadata of a first snapshot to determine validity of references in the metadata and a presence of any child of the first snapshot or a grandparent of the first snapshot. The system associates, based on the validity of the references in the metadata and the presence of any child or grandparent of the first snapshot, a hint with a metadata entry of a parent of the first snapshot to indicate that a metadata entry of the child or the grandparent is to be checked. The system updates, using the hint, the statistics relating to usage of storage space.
