Abstract: A computer or computer program product having a computer-readable medium comprising at least one controller to enable a processor to perform incremental changes storage and retrieval. The at least one controller comprises an incremental storage adaptor for enabling the processor to store a change associated with a base file, rather than modifying the base file by the change and storing the result as a new file. An incremental retrieval adaptor is included for enabling the processor to merge the change with the base file thereby forming a logical new file. The incremental retrieval adaptor can perform the merging in response to a call from an application running on the processor or another processor, and the incremental retrieval adaptor then provides or otherwise makes the logical new file available to the application.
