Abstract: Snapshot or point-in-time image functionality improves the use of object-based datastores. An example system includes an object-based datastore and a metadata datastore associated with the object-based datastore. Instances of the metadata datastore each identify the distributed data blocks that respectively store the objects included in the object-based datastore. An instance of the metadata datastore is used as a snapshot image of a set of objects of the object-based datastore based on identifying the distributed data blocks that were mapped to the set of objects during a point in time. A different instance of the metadata datastore is dynamically updated to reflect present mappings of distributed data blocks to objects in the object-based datastore. Different instances of the metadata datastore are used to read objects from previous timepoints, restore the object-based datastore to a previous snapshot image, enable intelligent deletion of objects of the object-based data store, and more.
