Summary:A method, apparatus, and computer instructions for managing versioning data for memory segments. Responsive to a request from a requester to allocate a memory segment, the memory segment is allocated. A versioning data structure is created for the memory segment. The versioning data structure is used to store changes in data for the memory segment, and the memory segment includes a pointer to the versioning data structure. When a change in the data is detected for the memory segment, wherein the change in the data forms the delta data. Responsive to detecting the change in the data for the memory segment, the delta data is stored in the versioning data structure, wherein the versioning data structure is used to return the data in the memory segment to a prior state.
