A method and system for providing delta-versioning of data stored in an object-based data repository. In the preferred embodiment, delta-versioning is provided for "file" objects in a PCTE implementation in a manner which is relatively versatile for developers of PCTE compliant tools and programs and which is largely transparent to the users of those tools and programs. Further, redundant restoration of delta-versioned data is minimized and automatic removal restored data which is no longer needed is provided.
