Abstract
A system, method, and computer program product for establishing a memory-mapped file, enabling the memory-mapped file data to be paged to a non-volatile storage medium, marking a portion of the memory-mapped file as protected, wherein a write to the memory mapped file throws a segmentation fault; receiving a write at the memory mapped file, throwing a segmentation fault; and handling the segmentation fault in a segmentation handler, where the handling comprises reading the information in the memory mapped file facility into the undo log, and writing the write IO to the storage medium.
