Abstract: System and method for converting a storage object in a redo-log snapshot format to a single-container snapshot format in a distributed storage system uses a temporary snapshot object, which is created by taking a snapshot of the storage object, and an anchor object, which points to a root object of the storage object. For each object chain of the storage object, each selected object is processed for format conversion. For each selected object, difference data between the selected object and a parent object of the selected object is written to the anchor object, a child snapshot of the anchor object is created in the single-container snapshot format, and the anchor object is updated to point to the selected object. The data of the running point object of the storage object is then copied to the anchor object, and each processed object and the temporary snapshot object are removed.
