Techniques for improving dirty page logging are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for memory logging comprising the steps of determining for one or more pages of memory if the pages of memory are likely to be modified in a subsequent epoch, performing a first operation on the pages of memory that are likely to be modified in a subsequent epoch, and performing a second operation on the pages of memory that are not likely to be modified in a subsequent epoch, wherein the first operation and the second operation are dissimilar.
