Abstract
A method, system, computer system, and computer-readable medium that identify the number of times areas of storage are updated and use that information to synchronize primary and secondary storage areas. The invention enables quick resumption of operations upon a discovery that primary and secondary data have become unsynchronized. Regions of storage that are unsynchronized can be identified quickly without the need to read the change log. In addition, data are copied efficiently, with minimal or no duplication of effort or data. Faster and more reliable storage can be allocated for storing regions of data that are 'hot spots,' thereby making better use of existing storage resources and budgets.
