Abstract: Techniques are provided for determining a physical size of a snapshot backed up to an object store. Snapshot data of the snapshot may be backed up into objects that are stored from a node to the object store, such as a cloud computing environment. A tracking object is created to identify which objects within the object store comprise the snapshot data of the snapshot. In order to determine the physical size of the snapshot, the tracking object and/or tracking objects of other snapshots such as a prior snapshot are evaluated to identify a set of objects comprising snapshot data unique to the snapshot and not shared with the prior snapshot. The physical sizes of the set of objects are combined with a metadata size of metadata of the snapshot to determine the physical size of the snapshot.
