Microsoft has successfully employed this approach in Windows 11, providing a 40% reduction in update size. "For versioned data systems requiring forward and reverse delta pairs, "reverse update data generation" provides a way of efficiently distributing the forward delta to the machine and having the machine maintain a path back to its original state. He concludes by explaining that Microsoft significantly reduced the size of updates via reverse mapping of virtual address in memory. This can be done in-place, and the reverse mapping will provide nearly the same performance as a reverse delta with a direct mapping from a delta generation done on the server." There is a slight overhead as not all mappings are 1:1, and where forward mapping conflicts with its observed reverse mapping, additional patch instruction must be used to align the mapping. "Much like the basic patching instructions, these transforms can be "observed" and reversed. Microsoft's Windows shrinkage technique, in the end, relied on "reverse mapping" the assembly of virtual addresses.
