Abstract:
Provided are a computer program product, system and method for retaining versions of an object. Changes are appended to a current version object resulting in a new current version object and a most recent previous version object comprising the current version object before the changes were appended. Version metadata, for each previous version object, includes the most recent previous version object, indicating an offset in the new current version object at which the previous version object can be recovered. The most recent previous version object is deleted and the version metadata, for the most recent previous version object after the most recent previous version object is deleted, is retained to allow recovery of a previous version object from the new current version object using the offset in the version metadata.
